[PATCH] block: remove typo in kernel-doc of set_disk_ro()

Commit 52f019d43c22 ("block: add a hard-readonly flag to struct gendisk")
provides some kernel-doc for set_disk_ro(), but introduces a small typo.

Hence, make htmldocs warns on ./block/genhd.c:1441:

  warning: Function parameter or member 'read_only' not described in 'set_disk_ro'
  warning: Excess function parameter 'ready_only' description in 'set_disk_ro'

Remove that typo in the kernel-doc for set_disk_ro().
