powerpc: Fix inverted SET_FULL_REGS bitop
commit 73ac79881804eed2e9d76ecdd1018037f8510cb1 upstream.
This bit operation was inverted and set the low bit rather than
cleared it, breaking the ability to ptrace non-volatile GPRs after
exec. Fix.
Only affects 64e and 32-bit.
Fixes: feb9df3462e6 ("powerpc/64s: Always has full regs, so remove remnant checks")
