net: stmmac: mmc: Remove duplicate mmc_rx crc

Browse source

MMC_XGMAC_RX_CRC_ERR is clear-on-read, and just a single read would
update the mmc_rx_crc_error counter.

The duplicate read appears to have been unintentionally introduced in
the intial MMC counter implementation [1]. The databook does not mention
MMC_XGMAC_RX_CRC_ERR needing the additional read.
