Replaced a call to malloc() and its respective call to free() with g_malloc() and g_free().

Signed-off-by: dinglimin <dinglimin@cmss.chinamobile.com>

v4 -> V5:Use g_try_malloc() instead of malloc()
V3 -> V4:Delete null checks after g malloc().
V2 -> V3:softmmu_unlock_user changes free to g free.
V1 -> V2:if cpu_memory_rw_debug failed, still need to set p=NULL
