commit a36e07dfe6ee71e209383ea9288cd8d1617e14f9 upstream.

The definition of RFKILL_IOCTL_MAX_SIZE introduced by commit
54f586a91532 ("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.
