The following patches were made over Linus's tree and also apply over
Jens's for-6.7/block and io_uring branches. They allow users to
configure the max number of ublk devices. We are currently converting
users from tcmu to ublk so the 64 device limit is too small, because we
have setups that have 512-1k devices.

V2:
- Set UBLK_MAX_UBLKS to UBLK_MINORS.
- Use param_set_uint_minmax.
