ext4: Rename and document EXT4_EX_FILTER to EXT4_EX_QUERY_FILTER
Rename EXT4_EX_FILTER to EXT4_EX_QUERY_FILTER to better describe its
purpose as a filter mask used specifically in ext4_map_query_blocks().
Add a comment explaining that this macro is used to filter flags needed
when querying the on-disk extent tree.
We will later use EXT4_EX_QUERY_FILTER mask to add another
EXT4_GET_BLOCKS_QUERY needed to lookup in on-disk extent tree.
