tty: hvc-iucv: Remove KMSG_COMPONENT macro 

The KMSG_COMPONENT macro is a leftover of the s390 specific "kernel message
catalog" from 2008 [1] which never made it upstream.

The macro was added to s390 code to allow for an out-of-tree patch which
used this to generate unique message ids. Also this out-of-tree doesn't
exist anymore.

Remove the macro in order to get rid of a pointless indirection.
