List below is output from C=2 sparse compilation, which are fixed with
this patch.

1) mptspi: pg0 is defined in x86 version of include/asm/pgtable.h

2) mptsas: context imbalance in 'mptsas_probe' different lock contexts
   for basic block

3) mptbase: from mpt_attach - cast adds address space to expression

4) mptbase: from mpt_do_upload - request[] is bad constant expression

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.

- i2o_msg_get_wait() return vaile is not checked;
- i2o_message memory leaks on error paths;
- infinite loop to sg_list_cleanup in passthru32

It's important issue because of i2o_cfg_passthru is used by raidutils for
monitorig controllers state, and in case of memory shortage it leads to the
node crash or disk IO stall.
