[Tarantool-patches] [PATCH v2] test: cleanup box/net.box_call_blocks_gh-946

[Alexander V. Tikhonov]

Found issue with 'readahead limit is reached':

 iproto iproto.cc:606 W> stopping input on connection fd 23, aka unix/:(socket), peer of unix/:(socket), readahead limit is reached

While the test doesn't check it. To fix the issue increased
'readahead' value.

Found issue at the tests running after the current test:

 main/435/console/unix/: utils.c:1005 E> LuajitError: [string "function on_disconnect() disconnected = true ..."]:1: assign to undeclared variable 'disconnected'

Found that the root cause of the issue, that tests run on the same
worker, in this case function on_disconnected must be cleaned.
Also clean up of the test at its end improved.
