If cpu->host_phys_bits_limit is set, QEMU will make
cpu->phys_bits be lower than host_phys_bits on some cases.  This
triggers a warning that was supposed to be printed only if
phys-bits was explicitly set in the command-line.

Reorder the code so the value of cpu->phys_bits is validated
before the cpu->host_phys_bits handling.  This will avoid
unexpected warnings when cpu->host_phys_bits_limit is set.
