[PATCH v2] hw/i386/pc: Remove vmport value assertion


From: Kamil Szczęk
Subject: [PATCH v2] hw/i386/pc: Remove vmport value assertion
Date: Tue, 20 Aug 2024 23:11:24 +0000

There is no need for this assertion here, as we only use vmport value
for equality/inequality checks. This was originally prompted by the
following Coverity report:
 >>> CID 1559533:  Integer handling issues (CONSTANT_EXPRESSION_RESULT)
 >>> "pcms->vmport >= 0" is always true regardless of the values of
 >>> its operands. This occurs as the logical first operand of "&&".
