mm: page_alloc: determine migratetype only once
The check for ALLOC_CMA in __alloc_pages_nodemask() derives migratetype
from gfp_mask in each retry pass, although the migratetype variable
already has the value determined and it does not change. Use the variable
and perform the check only once. Also convert #ifdef CONFIG_CMA to
IS_ENABLED.
