extcon: Return error code on failure
Function get_zeroed_page() returns a NULL pointer if there is no enough memory. In function extcon_sync(), it returns 0 if the call to get_zeroed_page() fails. The return value 0 indicates success in the context, which is incosistent with the execution status. This patch fixes the bug by returning -ENOMEM.
