I have increased the timeout to 10 minutes but it did not help.
Same error found.
[  608.679353] mmc1: Card stuck being busy! mmc_poll_for_busy
[  608.684964] mmc1: cache flush error -110
[  608.689005] blk_update_request: I/O error, dev mmcblk1, sector
4302400 op 0x1:(WRITE) flags 0x20800 phys_seg 1 prio class 0

OTOH, What best i could do for my own experiment to revert all three patches and
now the reported error gone and device mount successfully [1].

List of patches reverted,
  mmc: core: Specify timeouts for BKOPS and CACHE_FLUSH for eMMC
  mmc: block: Use generic_cmd6_time when modifying
    INAND_CMD38_ARG_EXT_CSD
  mmc: core: Default to generic_cmd6_time as timeout in __mmc_switch()
