ext4: remove unnecessary drop path references in mext_check_coverage()

According to Jan Kara's suggestion:
"The use in mext_check_coverage() can be actually removed
- get_ext_path() -> ext4_find_extent() takes care of dropping the references."
So remove unnecessary call ext4_ext_drop_refs() in mext_check_coverage().
