Use of the indirect call wrappers in some dst related functions for the
ipv6/ipv4 case. This is a small improvent for CONFIG_RETPOLINE=y

Changed in v2:
-fix build issues reported by kernel test robot

brianvv (4):
  net: use indirect call helpers for dst_input
  net: use indirect call helpers for dst_output
  net: use indirect call helpers for dst_mtu
  net: indirect call helpers for ipv4/ipv6 dst_check functions
