ext4: fix memory leak in ext4_free_branches
Commit 40389687 moved a call to ext4_forget() out of ext4_free_branches and let ext4_free_blocks() handle calling bforget(). But that change unfortunately did not replace the call to ext4_forget() with brelse(), which was needed to drop the in-use count of the indirect block's buffer head, which lead to a memory leak when deleting files that used indirect blocks. Fix this. Thanks to Hugh Dickins for pointing this out. Cc: stable@kernel.org Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
