MIPS: perf: Remove unnecessary "fallthrough" pseudo keywords
The last branch of switch-case doesn't need a "fallthrough" pseudo
keyword, and it will cause errors when building a kernel with -Werror:
arch/mips/kernel/perf_event_mipsxx.c: In function 'reset_counters':
include/linux/compiler_attributes.h:200:41: error: attribute 'fallthrough' not preceding a case label or default label [-Werror]
200 | # define fallthrough __attribute__((__fallthrough__))
| ^~~~~~~~~~~~~
>> arch/mips/kernel/perf_event_mipsxx.c:932:3: note: in expansion of macro 'fallthrough'
932 | fallthrough;
| ^~~~~~~~~~~
arch/mips/kernel/perf_event_mipsxx.c: In function 'loongson3_reset_counters':
include/linux/compiler_attributes.h:200:41: error: attribute 'fallthrough' not preceding a case label or default label [-Werror]
200 | # define fallthrough __attribute__((__fallthrough__))
| ^~~~~~~~~~~~~
arch/mips/kernel/perf_event_mipsxx.c:903:3: note: in expansion of macro 'fallthrough'
903 | fallthrough;
| ^~~~~~~~~~~
cc1: all warnings being treated as errors
Fix it by removing unnecessary "fallthrough" pseudo keywords.
