ext4: Simplify last in leaf check in ext4_map_query_blocks

This simplifies the check for last in leaf in ext4_map_query_blocks()
and fixes this cocci warning.

cocci warnings: (new ones prefixed by >>)
>> fs/ext4/inode.c:573:49-51: WARNING !A || A && B is equivalent to !A || B

Fixes: 5bb12b1 ("ext4: Add support for EXT4_GET_BLOCKS_QUERY_LEAF_BLOCKS")
