This happens if a client migrates a connection to PreferredAddress. One QUICPacketHandler is created for each server addresses and ports, and QUICNetVC has a pointer for one of them at the beginning of a connection. If a client migrate to another address or port, the pointer QUICNetVC holding has to be updated to the one for the new port and address.

Added these asserts and neither of them failed.
ink_assert(mutex != nullptr);
ink_assert(c->mutex != nullptr);
