[ Upstream commit 411dac79cc2ed80f7e348ccc23eb4d8b0ba9f6d5 ]
Add missing clearing of BLTZALL and BGEZALL emulation counters in function mipsr2_stats_clear_show().
Previously, it was not possible to reset BLTZALL and BGEZALL emulation counters - their value remained the same even after explicit request via debugfs. As far as other related counters are concerned, they all seem to be properly cleared.
This change affects debugfs operation only, core R2 emulation functionality is not affected.
