rfkill: uapi: fix RFKILL_IOCTL_MAX_SIZE ioctl request definition

commit 87804a8176130724d1b4f15be521e76b4cefb002 upstream.

The definition of RFKILL_IOCTL_MAX_SIZE introduced by commit
9379e4c9cc63 ("rfkill: make new event layout opt-in") is unusable
since it is based on RFKILL_IOC_EXT_SIZE which has not been defined.
Fix that by replacing the undefined constant with the constant which
is intended to be used in this definition.
