[GIT PULL] KEYS: fixes for v5.1

[James Morris]

Hi Linus,

Please pull these fixes for the Keys subsystem.

>From David Howells:

" (1) Handle quotas better, allowing full quota to be reached.

 (2) Fix the creation of shortcuts in the assoc_array internal
     representation when the index key needs to be an exact multiple of the
     machine word size.

 (3) Fix a dependency loop between the request_key contruction record and
     the request_key authentication key.  The construction record isn't
     really necessary and can be dispensed with.

 (4) Set the timestamp on a new key rather than leaving it as 0.  This
     would ordinarily be fine - provided the system clock is never set to a
     time before 1970."
