Masahiro Yamada 04aaca197f char: raw: do not leak CONFIG_MAX_RAW_DEVS to userspace ...

include/uapi/linux/raw.h leaks CONFIG_MAX_RAW_DEVS to userspace.

Userspace programs cannot use MAX_RAW_MINORS since CONFIG_MAX_RAW_DEVS
is not available anyway.

Remove the MAX_RAW_MINORS definition from the exported header, and use
CONFIG_MAX_RAW_DEVS in drivers/char/raw.c

While I was here, I converted printk(KERN_WARNING ...) to pr_warn(...)
and stretched the warning message.
