Memmap: Don't show panic alert for 0 length range

Browse Source 
IOS::HLE::IOCtlVRequest::Dump sometimes tries to call GetPointerForRange
with an address of 0 and a size of 0. Address 0 is valid, but we were
mistakenly also trying to check that address 3FFFFFFF is valid, which it
isn't.

Fixes https://bugs.dolphin-emu.org/issues/13514.
