Heiko Carstens 5c345c47e8 s390: Initialize psw mask in perf_arch_fetch_caller_regs() ...

[ Upstream commit 223e7fb979 ]

Also initialize regs->psw.mask in perf_arch_fetch_caller_regs().
This way user_mode(regs) will return false, like it should.

It looks like all current users initialize regs to zero, so that this
doesn't fix a bug currently. However it is better to not rely on callers
to do this.
