libxfs: propagate transaction block reservations
Certain parts of the libxfs preemptively refuse to run if the
transaction block reservation has fallen to zero. We leave t_blk_res at
its default of zero, which means that these code paths always fail even
if the transaction was allocated with a non-zero block reservation. Set
t_blk_res and maintain it through transaction rolls, even though we
don't do much enforcement the transaction block limits.
[sandeen: This broke during a libxfs sync to userspace, see Fixes:]
