staging: android: ion: Return an ERR_PTR in ion_map_kernel
commit 0a2bc00341dcfcc793c0dbf4f8d43adf60458b05 upstream.
The expected return value from ion_map_kernel is an ERR_PTR. The error
path for a vmalloc failure currently just returns NULL, triggering
a warning in ion_buffer_kmap_get. Encode the vmalloc failure as an ERR_PTR.
