spi: pic32: Fix checking return value of devm_ioremap_resource
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. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Mark Brown <broonie@kernel.org>
