A typo caused the interrupt handler to branch immediately to the common

This does not affect KVM softpatch handling (e.g., for POWER9 TM assist)
because the KVM test was moved to common code by commit 9600f261acaa
("powerpc/64s/exception: Move KVM test to common code") just before this
bug was introduced.

Applied to powerpc/fixes.
