[PATCH 1/2] [btrfs] btrfs_rename: abort transaction in case of error.

["Davide C. C. Italiano" <dccitaliano@gmail.com>]

From: Davide Italiano <dccitaliano@gmail.com>

btrfs_insert_inode_ref() may fail and we want to make sure
the transaction is aborted before calling btrfs_end_transaction(),
as it already happens everywhere else in this function in case
of error.
