when probe a pci device, first we enable it, and disable it when
some error happened in the following process, because the power
state of the device is set to D0, and if MSI is disabled,
we will allocate irq and register gsi for this device in the enable process.

In function mpt_mapresources(MPT_ADAPTER *ioc), it forgot disable the
pci device when error happened, the irq and gsi will never be released.
this patch will fix it.

The device limit of 128 tape drives was established in 2003 as a
significant increase from the 8 tape drives allowed previously.

We're seeing customer sites that between a large number of drives
and multipath are discovering more than 128 devices and running
into problems.

Now that we're not stuck having to store a pointer in array
and aren't limited by kmalloc failing on higher order allocs we can
lift the limit to fill the entire minor range based on the number
of modes.

Based on the current code, that's 2^17 devices.

st currently allocates an array to store pointers to all of the
scsi_tape objects. It's used to discover available indexes to use as the
base for the minor number selection and later to look up scsi_tape
devices for character devices.

We switch to using an IDR for minor selection and a pointer from
st_modedef back to scsi_tape for the lookups.

st_probe leaves a cdev pointer hanging around that is compared
during the error path and freed later. There's no need for the pointer
to hang around at all. So we free it immediately and simplify the error
handling.

lead to change in the value.This changed value is passed
