scsi: ufs: core: Remove an unnecessary NULL pointer check

The !payload check tests the address of a member of a data structure. We
know that the start address of this data structure (job) is not NULL
since the 'job' pointer has already been dereferenced. Hence, the
!payload check is superfluous. Remove this test. This was reported by
the CodeSonar static analyzer.
