mips/oprofile: Fix fallthrough placement
We want neither " include/linux/compiler_attributes.h:201:41: warning: statement will never be executed [-Wswitch-unreachable] 201 | # define fallthrough __attribute__((__fallthrough__)) | ^~~~~~~~~~~~~ " nor " include/linux/compiler_attributes.h:201:41: warning: attribute 'fallthrough' not preceding a case label or default label 201 | # define fallthrough __attribute__((__fallthrough__)) | ^~~~~~~~~~~~~ " It's not worth adding one more macro. Let's simply place the fallthrough in between the expansions.
