crypto: x86 - Add missing RETs

Add explicit RETs to the tail calls of AEGIS and MORUS crypto algorithms
otherwise they run into INT3 padding due to

  ("x86/asm: Pad assembly functions with INT3 instructions")

leading to spurious debug exceptions.

Mike Galbraith <efault@gmx.de> took care of all the remaining callsites.
