MIPS: Fix delay slot emulation count in debugfs
Commit 432c6bacbd0c ("MIPS: Use per-mm page to execute branch delay slot
instructions") accidentally removed use of the MIPS_FPU_EMU_INC_STATS
macro from do_dsemulret, leading to the ds_emul file in debugfs always
returning zero even though we perform delay slot emulations.
Fix this by re-adding the use of the MIPS_FPU_EMU_INC_STATS macro.
