Heiko Carstens 318ca89bc5 s390: Initialize psw mask in perf_arch_fetch_caller_regs() 
[ Upstream commit 223e7fb979fa06934f1595b6ad0ae1d4ead1147f ]

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.
