scsi: ufs: core: Add NULL check in ufshcd_mcq_compl_pending_transfer()
[ Upstream commit 08a966a917fe3d92150fa3cc15793ad5e57051eb ]
Add a NULL check for the returned hwq pointer by ufshcd_mcq_req_to_hwq().
This is similar to the fix in commit 74736103fb41 ("scsi: ufs: core: Fix
ufshcd_abort_one racing issue").
