Drop Pantry locks before Volume operations#1952

Holding the `entries` lock across an activation or deactivation will lock out _all_ other Pantry operations. If a activation or deactivation can not complete, this makes the Pantry un-usable. Drop the mutex guards before long-running operations. Also: in the Pantry implementation, re-implement `attach` in terms of `attach_activate_background`, which already does the activation in the background and drops the `entries` lock. However callers of `attach` expect the Volume to be activated when the call returns so wait for the background job. Co-authored-by: Alan <alan@oxide.computer> Fixes oxidecomputer#1945.

There was a problem hiding this comment.
I would like the pantry test in here as well, but I can add that in a follow up PR.
