block: fix kernel-doc for disk_force_media_change()

Drop one function parameter's kernel-doc comment since the parameter
was removed. This prevents a kernel-doc warning:

block/disk-events.c:300: warning: Excess function parameter 'events' description in 'disk_force_media_change'

Fixes: ab6860f6 ("block: simplify the disk_force_media_change interface")
