MIPS: ralink: Fix request_mem_region error handling
request_mem_region returns a NULL pointer on error, comparing it
against a number results in a warning:
arch/mips/ralink/of.c: In function 'plat_of_remap_node':
arch/mips/ralink/of.c:45:15: error: ordered comparison of pointer with integer zero [-Werror=extra]
arch/mips/ralink/irq.c: In function 'intc_of_init':
arch/mips/ralink/irq.c:167:15: error: ordered comparison of pointer with integer zero [-Werror=extra]
