mips: asm: fix warning when disabling MIPS_FP_SUPPORT
When MIPS_FP_SUPPORT is disabled, __sanitize_fcr31() is defined as
nothing, which triggers a gcc warning:
In file included from kernel/sched/core.c:79:
kernel/sched/core.c: In function 'context_switch':
./arch/mips/include/asm/switch_to.h:114:39: warning: suggest braces around empty body in an 'if' statement [-Wempty-body]
114 | __sanitize_fcr31(next); \
| ^
kernel/sched/core.c:5316:9: note: in expansion of macro 'switch_to'
5316 | switch_to(prev, next, prev);
| ^~~~~~~~~
Fix this by providing an empty body for __sanitize_fcr31() like one is
defined for __mips_mt_fpaff_switch_to().
Fixes: 36a498035bd2 ("MIPS: Avoid FCSR sanitization when CONFIG_MIPS_FP_SUPPORT=n")
