mmc: core: Remove struct mmc_context_info

The 'mmc_context_info' structure is unused.

It has been introduced in:

  - commit 2220eedf ("mmc: fix async request mechanism for sequential
    read scenarios")

in 2013-02 and its usages have been removed in:

  - commit 126b6270 ("mmc: core: Remove code no longer needed after the
    switch to blk-mq")
  - commit 0fbfd125 ("mmc: block: Remove code no longer needed after
    the switch to blk-mq")

in 2017-12.

Now remove this unused structure.
