[comboot] Reset console before starting COMBOOT executable
iPXE does not call shutdown() before invoking a COMBOOT executable,
since the executable is allowed to make API calls back into iPXE. If
a background picture is used, then the console will not be restored to
text mode before invoking the COMBOOT executable. This can cause
undefined behaviour.
Fix by adding an explicit call to console_reset() immediately before
invoking a COMBOOT or COM32 executable, analogous to the call made to
console_reset() immediately before invokving a PXE NBP.
