ext4: refactor ext4_collapse_range()

Browse source

[ Upstream commit 162e3c5ad1 ]

Simplify ext4_collapse_range() and align its code style with that of
ext4_zero_range() and ext4_punch_hole(). Refactor it by: a) renaming
variables, b) removing redundant input parameter checks and moving
the remaining checks under i_rwsem in preparation for future
refactoring, and c) renaming the three stale error tags.
