scsi: pm8001: Fix pm8001_tag_alloc() failures handling
In mpi_set_phy_profile_req() and in pm8001_set_phy_profile_single(), if
pm8001_tag_alloc() fails to allocate a new tag, a warning message is issued
but the uninitialized tag variable is still used to build a command. Avoid
this by returning early in case of tag allocation failure.
Also make sure to always return the error code returned by
pm8001_tag_alloc() when this function fails instead of an arbitrary value.
