selftests: ublk: move zero copy feature check into _add_ublk_dev()

Browse source

Move zero copy feature check into _add_ublk_dev() since we will have
more tests which requires to cover zero copy.

Then one check function of _check_add_dev() has to be added for dealing
with cleanup since '_add_ublk_dev()' is run in sub-shell, and we can't
exit from it to terminal shell.

Meantime always return error code from _add_ublk_dev().
