[PATCH] input: tablet: aiptek: Replace GFP_ATOMIC with GFP_KERNEL in aiptek_probe()

[Jia-Ju Bai]

aiptek_probe() 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.
