[PATCH] scsi: fnic: Use kmalloc instead of vmalloc for a small memory allocation

From: Christophe JAILLET
Date: Thu Apr 23 2020 - 16:46:26 EST


'struct fc_trace_flag_type' is just a few bytes long. There is no need
to allocate such a structure with vmalloc. Using kmalloc instead.

While at it, axe a useless test when freeing the memory.
