[Tarantool-patches] [PATCH 1/4] box/txn: fix void args mess

[Cyrill Gorcunov]

Using void explicitly in functions which take
no arguments allows to optimize code a bit and
don't assume if there might be variable args.

Moreover in commit e070cc4d9 we dropped arguments
from txn_begin but didn't update vy_scheduler.c.
The compiler didn't complain because it assumed
there are vargs.
