[PATCH 2/2] atm: fore200e: Replace GFP_ATOMIC with GFP_KERNEL in fore200e_send

[Jia-Ju Bai]

After checking all possible call chains to fore200e_send here,
my tool finds that fore200e_send is never called in atomic context.
And this function is assigned to a function pointer "dev->ops->send",
which is only called by vcc_sendmsg (net/atm/common.c) 
through vcc->dev->ops->send, and vcc_sendmsg calls schedule,
it indicates that fore200e_send 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.
