[PATCH -next] mtd: plat_nand: remove redundant return value check of platform_get_resource()

From: Wei Yongjun <yongjun_wei@trendmicro.com.cn>

Remove unneeded error handling on the result of a call
to platform_get_resource() when the value is passed to
devm_ioremap_resource(). And move those two call together
to make the connection between them more clear.
