xfs: ensure logflagsp is initialized in xfs_bmap_del_extent_real
In the case of returning -ENOSPC, ensure logflagsp is initialized by 0.
Otherwise the caller __xfs_bunmapi will set uninitialized illegal
tmp_logflags value into xfs log, which might cause unpredictable error
in the log recovery procedure.
Also, remove the flags variable and set the *logflagsp directly, so that
the code should be more robust in the long run.
