[PATCH -v2 1/2] ext4: Fix accounting of reserved metadata blocks

[Theodore Ts'o <tytso@mit.edu>]

Commit 0637c6f had a typo which caused the reserved metadata blocks to
not be released correctly.   Fix this.

Oops, I accidentally deleted an extra line that was critically needed in
the earlier -v1 version of this patch.
