mmc: host: remove mmcq performance numbers statistics
mmcq performance numbers are not captured since asynchronous
MMC request support got added in MMC block driver. So printing
out these numbers (which are all zeros) just adds confusion.
This patch removes the printing of mmcq performance numbers
statistics.
