BUG/MINOR: checks: Properly handle truncated mysql server messages

Browse Source 
If a message is not fully received from a mysql server, depending on last_read
value, an error must be reported or we must wait for more data. The first if
statement must not check last_read.

Partly fixes issue #600. No backport needed.
