Minhong He 12324f00a8 ipv6: sr: validate HMAC algorithm ID in seg6_hmac_info_add
[ Upstream commit 84967deee9 ]

The seg6_genl_sethmac() directly uses the algorithm ID provided by the
userspace without verifying whether it is an HMAC algorithm supported
by the system.
If an unsupported HMAC algorithm ID is configured, packets using SRv6 HMAC
will be dropped during encapsulation or decapsulation.
