[PATCH] QE: Use GFP_ATOMIC under spin lock

[weiyj_lk at 163.com]

From: Wei Yongjun <yongjun_wei at trendmicro.com.cn>

The function cpm_muram_alloc_common() is called from several
places, in some of which, such as cpm_muram_alloc(), a lock is
held here, so we should use GFP_ATOMIC when a lock is held.
