LU-15055 lod: run qmt_pool_* only from the MDT0000 config

On the first mds (with MDT0000/QMT0000), if there is more than one MDT
target, qmt_pool_{new/del/rem/add} functions will be call several
times on QMT0000 for the same pool.

This resulting to the following error in dmseg:
LustreError: 5659:0:(qmt_pool.c:1390:qmt_pool_add_rem()) add to: can't
scratch-QMT0000 scratch-OST0000_UUID pool pool1: rc = -17

This patch run qmt_pool_* only from a record config from the MDT0000.
The qmt_pool_add_rem() dmesg error is checked on sanity-quota test_1b.
