[PATCH] input: misc: powermate: Replace GFP_ATOMIC with GFP_KERNEL in powermate_alloc_buffers()

[Jia-Ju Bai]

powermate_alloc_buffers() is never called in atomic context.
It calls usb_alloc_coherent() with GFP_ATOMIC, which is not necessary.
GFP_ATOMIC can be replaced with GFP_KERNEL.

This is found by a static analysis tool named DCNS written by myself.
