[PATCH] spi: pic32: Fix checking return value of devm_ioremap_resource

[Axel Lin <axel.lin-8E1dMatC8ynQT0dZR+AlfA@public.gmane.org>]

devm_ioremap_resource() returns ERR_PTR on error.
Also remove the redundant dev_err message, the implementation of
devm_ioremap_resource() already print error messages on error paths.
