Warning if LSX server port couldn't be bound

[p0358]

A user might be running the real EA App from some WINE prefix in the background and it might already be occupying the port, which will log this error in console:

ERROR - [maxima-lib/src/core/mod.rs:237] - Error starting LSX server: Address already in use (os error 98)

Eventually some warning dialog in the UI could be added for the users to not be caught off-guard by this (I thiiiiink Origin itself could have been refusing to start up completely if that was the case, though apparently also without a visible error aka https://forums.ea.com/discussions/battlefield-v-en/bfv-not-starting-lsx-server-port-3216/6781209 )

Very minor and low priority thing.
