sparc64: Don't clibber fixed registers in __multi4.
commit 79db795833bf5c3e798bcd7a5aeeee3fb0505927 upstream.
%g4 and %g5 are fixed registers used by the kernel for the thread
pointer and the per-cpu offset. Use %o4 and %g7 instead.
Diagnosis by Anthony Yznaga.
Fixes: 1b4af13ff2cc ("sparc64: Add __multi3 for gcc 7.x and later.")
