s390/ftrace: make use of epsw to get psw mask
Finally use epsw to create a complete psw mask within pt_regs. Without
this only some bits are correct, while other bits are (incorrectly)
always zero.
The epsw instruction is quite heavy weight, however given that this
only effects ftrace_regs_caller this seems to be the right thing, so
we finally get a complete psw mask for ftrace kprobed functions.
