mmc: block: Use MQRQ_XFER_SINGLE_BLOCK for both read and write recovery

Currently, the code uses the MQRQ_XFER_SINGLE_BLOCK flag to handle write
failures by retrying with single-block transfers. However, read failures
bypass this mechanism and instead use a dedicated legacy path mmc_blk_read_single()
that performs sector-by-sector retries.

Extend the MQRQ_XFER_SINGLE_BLOCK logic to cover multi-block read failures
as well. By doing so, we can remove the redundant and complex mmc_blk_read_single()
function, unifying the retry logic for both read and write operations under
a single, consistent, easier-to-maintain mechanism.
