f2fs: Use mapping->gfp_mask to get file cache for writing
On 32-bit architectures, when GFP_NOFS is used, the file cache for write
operations cannot be allocated from the highmem and CMA.
Since mapping->gfp_mask is set to GFP_HIGHUSER_MOVABLE during inode
allocation, using mapping_gfp_mask(mapping) as the GFP flag of getting file
cache for writing is more efficient for 32-bit architectures.
Additionally, use FGP_NOFS to avoid potential deadlock issues caused by
GFP_FS in GFP_HIGHUSER_MOVABLE
