include/linux/gfp.h: fix the annotation of GFP_ZONE_TABLE
When bit is equal to 0x4, it means OPT_ZONE_DMA32 should be got from
GFP_ZONE_TABLE. OPT_ZONE_DMA32 shall be equal to ZONE_DMA32 or
ZONE_NORMAL according to the status of CONFIG_ZONE_DMA32.
Similarly, when bit is equal to 0xc, that means OPT_ZONE_DMA32 should be
got with an allocation policy GFP_MOVABLE. So ZONE_DMA32 or ZONE_NORMAL
is the possible result value.
