ext4: remove metadata reservation checks
Commit 27dd43854227b ("ext4: introduce reserved space") reserves 2% of the file system space to make sure metadata allocations will always succeed. Given that, tracking the reservation of metadata blocks is no longer necessary. Signed-off-by: Theodore Ts'o <tytso@mit.edu>
