freebsd_network: Restore the hard-coded 128KB physical map size.

Browse Source 
mmu_man changed this to be dynamically computed based on the BAR size.
It seems his computation was somehow incorrect, as it tries to allocate
a very large region here which deadlocks in the physical memory mapper.
Restoring this to 128KB un-breaks the new ipro1000 driver on more
recent hardware.

"Fixes" #14795.
