Subject: [PATCH v1] usb: core: driver: Use kmalloc_array

Use kmalloc_array instead of kmalloc to allocate memory for an array.
Also, remove the dev_warn for a memory leak, making the if check more
sleek.

Signed-off-by: Muhammad Falak R Wani <falakreyaz@...il.com>

On suggestion by Joe Perches <joe@...ches.com>

Changes since v0
	-remove dev_warn for memory leak
	-remove unnecessary parens for if
