nfs4: Make uid and gid consistent for async IO

Browse Source 
* Allow the client of the Request constructor to specify the uid and
  gid to apply to a Request, regardless of the euid and egid that are
  in effect for the thread.
* For write and delegation recall requests, apply the IDs that were
  captured earlier by the OpenState or Delegation constructor,
  respectively.
* This prevents the server from denying requests sent by the WorkQueue
  thread based on the uid and gid in the RPC header.
* Fixes #19657.

The Linux server I use for testing never seems to grant the client a
delegation, so I wasn't able to test whether the server actually cares
about the uid and gid when a delegation is recalled.
