nvmet: add a clear_ids attribute for passthru targets
If the clear_ids attribute is set to true, the EUI/GUID/UUID is cleared
for the passthru target. By default, loop targets will set clear_ids to
true.
This resolves an issue where a connect to a passthru target fails when
using a trtype of 'loop' because EUI/GUID/UUID is not unique.
Fixes: 2079f41ec6ff ("nvme: check that EUI/GUID/UUID are globally unique")
