devm_memremap: Fix error value when memremap failed
commit 93f834df9c2d4e362dfdc4b05daa0a4e18814836 upstream.
devm_memremap() returns an ERR_PTR() value in case of error.
However, it returns NULL when memremap() failed. This causes
the caller, such as the pmem driver, to proceed and oops later.
Change devm_memremap() to return ERR_PTR(-ENXIO) when memremap()
failed.
