Btrfs: fix number of transaction units required to create symlink

commit 9269d12 upstream. We weren't accounting for the insertion of an inline extent item for the symlink inode nor that we need to update the parent inode item (through the call to btrfs_add_nondir()). So fix this by including two more transaction units. Signed-off-by: Filipe Manana <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
