Subject: [PATCH ipsec-next] xfrm: delete duplicated functions that calls same xfrm_api_check()

From: Leon Romanovsky <leonro@...dia.com>

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.

Fixes: 92a2320697f7 ("xfrm: check for xdo_dev_ops add and delete")
