ZTS: Remove TXG_TIMEOUT from dedup_quota test (#17150)

Browse Source 
It seems `fio` in `ddt_dedup_vdev_limit` overwhelms the system
with the amount of dirty data caused by DDT updates within one
TXG due to tiny 1KB records used, while I see no reason for this
test to extend the TXGs beyond default.
