s390: simplify early program check handler
Due to historic reasons the base program check handler calls a
configurable function. Given that there is only the early program
check handler left, simplify the code by directly calling that
function.
The only other user was removed with commit d485235b0054 ("s390:
assume diag308 set always works").
Also rename all functions and the asm file to reflect this.
