MdeModulePkg: Fix a performance data buffer overrun issue
The mBmPerfHeader.Count isn't reset to 0 in BmWriteBootToOsPerformanceData()
so when the actual performance data entry count exceeds the LimitCount,
the performance data collection breaks on condition
if (mBmPerfHeader.Count == LimitCount), but 2nd time calling this function
will not break on condition if (mBmPerfHeader.Count == LimitCount) because
the mBmPerfHeader.Count always bigger than LimitCount, which results buffer
overrun.
