ublk: fix ublksrv pid handling for pid namespaces
When ublksrv runs inside a pid namespace, START/END_RECOVERY compared
the stored init-ns tgid against the userspace pid (getpid vnr), so the
check failed and control ops could not proceed. Compare against the
caller’s init-ns tgid and store that value, then translate it back to
the caller’s pid namespace when reporting GET_DEV_INFO so ublk list
shows a sensible pid.
Testing: start/recover in a pid namespace; `ublk list` shows
reasonable pid values in init, child, and sibling namespaces.
Fixes: c2c8089f325e ("ublk: validate ublk server pid")
