misc: sram: fix check of devm_ioremap*() return value
Both devm_ioremap() and devm_ioremap_wc() functions return either
a pointer to valid iomem region or NULL, check for IS_ERR() is improper
and may result in oops on error path. Now on error -ENOMEM is returned.
Fixes: 0ab163ad1ea0 ("misc: sram: switch to ioremap_wc from ioremap")
