[PATCH] cifsd: use kfree to free memory allocated by kmalloc or kzalloc

[Muhammad Usama Anjum <musamaanjum@gmail.com>]

kfree should be used to free memory allocated by kmalloc or kzalloc to
avoid any overhead and for maintaining consistency.

Fixes: 5dfeb6d945 ("cifsd: use kmalloc() for small allocations")
