[088/165] ext4: Fix accounting of reserved metadata blocks

[Greg KH]

2.6.32-stable review patch.  If anyone has any objections, please let us know.

------------------

commit ee5f4d9cdf32fd99172d11665c592a288c2b1ff4 upstream (as of v2.6.33-rc3)

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