MIPS: Remove a warning when PHYS_OFFSET is 0x0
Rewrite the comparison in `else if` statement, case where `min_low_pfn >
ARCH_PFN_OFFSET` has already been checked in the first `if` statement:
if (min_low_pfn > ARCH_PFN_OFFSET) {
Fix non-fatal warning during compilation using W=1:
arch/mips/kernel/setup.c: In function ‘bootmem_init’:
arch/mips/kernel/setup.c:461:25: warning: comparison of unsigned expression < 0 is always false [-Wtype-limits]
} else if (min_low_pfn < ARCH_PFN_OFFSET) {
