[SRU][F:linux-bluefield][PATCH] UBUNTU: SAUCE: net/xfrm: Fix XFRM flags validity check

[Bodong Wang]

From: Emeel Hakim <ehakim at nvidia.com>

BugLink: https://bugs.launchpad.net/bugs/1978967

commit a3ca11eec78 introduced a flags validity check for xfrm,
the check excluded flag XFRM_OFFLOAD_FULL from the check hence the
flag is being blocked from getting to the kernel space.
The above is preventing ipsec states from being added with the
full_offload option hence the Failure.

Fix by adding XFRM_OFFLOAD_FULL flag to the check statement which
allows the flag to get to kernel space as expected.

Fixes: a3ca11eec78 ("xfrm: enforce validity of offload input flags")
