[Xenial,SRU] Xenial update to 4.4.90 stable release

BugLink: https://bugs.launchpad.net/bugs/1721550

Fixed up "KEYS: prevent creating a different user's keyrings" because
it failed to apply cleanly as we carry a delta for bug #1569924
"linux: Add UEFI keyring for externally signed modules".

Fixed up "cxl: Fix driver use count" because it failed to apply cleanly
as we carry a delta for bug #1588468 "CAPI: CGZIP AFU contexts do not
receive interrupts after heavy afu open/close".
