can: build proc support only if CONFIG_PROC_FS is activated

Browse source

When building can subsystem with CONFIG_PROC_FS=n I detected some unused
variables warning by using proc functions. In CAN the proc handling is
nicely placed in one object file. This patch adds simple add a
dependency on CONFIG_PROC_FS for CAN's proc.o file and corresponding
static inline no-op functions.
