[PATCH] sh: Remove long unused mid_sched macro

[Andreas Bombe <aeb@debian.org>]

interruptible_sleep_on() is referenced for use in the mid_sched macro
which is not used anywhere.  Remove reference and macro as well as the
comment which appears to belong with them.

At least the mid_sched name does not appear anywhere else.  It doesn't
even appear to have been in use at any time during the kernel's git
history.
