s390/cpum_sf: Rework call to sf_disable()

Browse Source 
Setup_pmc_cpu() function body consists of one single switch
statement with two cases PMC_INIT and PMC_RELEASE.
In both of these cases sf_disable() is invoked to turn off the
CPU Measurement sampling facility.
Move sf_disable() out of the switch statement.
No functional change.
