mon: disable gmt_hitset if not supported

the gmt_hitset is enabled by default in the ctor of pg_pool_t, this
is intentional. because we want to remove this setting and make
gmt_hitset=true as a default in future. but this forces us to
disable it explicitly when preparing a new pool if any OSD does
not support gmt hitset.

Fixes: #12968
