[PATCH 1/2] atm: fore200e: Replace GFP_ATOMIC with GFP_KERNEL in fore200e_open

[Jia-Ju Bai]

After checking all possible call chains to fore200e_open here,
my tool finds that fore200e_open is never called in atomic context.
And fore200e_open calls mutex_lock which can sleep later,
thus it is supposed fore200e_open can call functions which may sleep.
Thus GFP_ATOMIC is not necessary, and it can be replaced with GFP_KERNEL.

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