dm: don't change md if dm_table_set_restrictions() fails
[ Upstream commit 9eb7109a5bfc5b8226e9517e9f3cc6d414391884 ]
__bind was changing the disk capacity, geometry and mempools of the
mapped device before calling dm_table_set_restrictions() which could
fail, forcing dm to drop the new table. Failing here would leave the
device using the old table but with the wrong capacity and mempools.
Move dm_table_set_restrictions() earlier in __bind(). Since it needs the
capacity to be set, save the old version and restore it on failure.
Fixes: bb37d77239af2 ("dm: introduce zone append emulation")
