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.
