Subject: xfrm: delete duplicated functions that calls same xfrm_api_check()
Patch-mainline: v5.18-rc1
Git-commit: 2ecda181682e9ed66dfbd5f8445c5d5a35b984d3
References: jsc#PED-373

The xfrm_dev_register() and xfrm_dev_feat_change() have same
implementation of one call to xfrm_api_check(). Instead of doing such
indirection, call to xfrm_api_check() directly and delete duplicated
functions.
