The script "checkpatch.pl" pointed information out like the following.
WARNING: Possible unnecessary 'out of memory' message
Thus remove such a statement here.

Looks good to me.

PS: ufshcd_memory_alloc() also does some DMA coherent memory allocation
(via dmam_alloc_coherent() APIs) and tries to print out the message on
allocation failure. Although i don't know "out of memory" messages will
be printed out by dmam_alloc_coherent() APIs or not. If it does print it
out then we might want to remove our local memory allocation failure log
messages.
