The Coverity checker spotted two potential memory leaks in
drivers/message/fusion/mptbase.c::mpt_attach().

There are two returns that may leak the storage allocated for 'ioc'
(sizeof(MPT_ADAPTER) bytes).

A simple fix would be to simply add two kfree() calls before the return
statements, but a better fix (that this patch implements) is to reorder the
code so that if we hit the first return condition we don't have to do the
allocation at all and then just add a kfree() call for the second case.

srp transport works for target drivers without supported_mode

This adds minimum target driver support like the srp transport does:

- fc_remote_port_{rolechg,delete} calls
scsi_tgt_it_nexus_{create,destroy} for target drivers.

- add callbacks to notify target drivers of the nexus and tmf
operation results to fc_function_template.

This adds supported_mode and active_mode attributes to
/sys/class/sys_host/hostX/ for specifying the mode that a lld supports
and the currently activated mode. The output format is similar to fc
rport roles:

luce:/sys/class/scsi_host/host0$ cat supported_mode
Initiator
luce:/sys/class/scsi_host/host0$ cat active_mode
Initiator

The mode values uses bitmap since we would support dual-mode llds in
the future like this:

luce:/sys/class/scsi_host/host0$ cat supported_mode
Initiator, Target

The supported_mode attribute looks at a scsi_host_template and the
active_mode attribute looks at a scsi_host. We would add a hook to a
scsi_host_template to change the active_mode attribute
dynamically. But now there is no hook since no lld supports that
feature.

The Coverity checker noticed that we may overrun a statically allocated
array in drivers/scsi/lpfc/lpfc_sli.c::lpfc_sli_hbqbuf_find().

The case is this; In 'struct lpfc_hba' we have

	#define LPFC_MAX_HBQS  4
	...
	struct lpfc_hba {
		...
		struct hbq_s hbqs[LPFC_MAX_HBQS];
		...
	};

But then in lpfc_sli_hbqbuf_find() we have this code

	hbqno = tag >> 16;
	if (hbqno > LPFC_MAX_HBQS)
		return NULL;

if 'hbqno' ends up as exactely 4, then we won't return, and then this

	list_for_each_entry(d_buf, &phba->hbqs[hbqno].hbq_buffer_list, list) {

will cause an overflow of the statically allocated array at index 4,
since the valid indices are only 0-3.

I propose this patch, that simply changes the 'hbqno > LPFC_MAX_HBQS'
into 'hbqno >= LPFC_MAX_HBQS' as a possible fix.
