xfs: ensure committed is initialized in xfs_trans_roll
__xfs_trans_roll() can return without setting the
*committed argument; this was a problem for xfs_bmap_finish():
int committed;/* xact committed or not */
...
error = __xfs_trans_roll(tp, ip, &committed);
if (error) {
...
if (committed) {
and we tested an uninitialized "committed" variable on the
error path. No caller is preserving "committed" state across
calls to __xfs_trans_roll(), so just initialize committed inside
the function to avoid future errors like this.
