nvme: fix kernel memory corruption with short INQUIRY buffers
If userspace asks for an INQUIRY buffer smaller than 36 bytes, the SCSI
translation layer will happily write past the end of the INQUIRY buffer
allocation.
This is fairly easily reproducible by running the libiscsi test
suite and then starting an xfstests run.
