mmc: sdhci-esdhc-imx: correct CQHCI exit halt state check
With the current logic the "failed to exit halt state" error would be
shown even if any other bit than CQHCI_HALT was set in the CQHCI_CTL
register, since the right hand side is always true. Fix this by using
the correct operator (bit-wise instead of logical AND) to only check for
the halt bit flag, which was obviously intended here.
