[PATCH] zram: Remove KMSG_COMPONENT macro

[Heiko Carstens <hca@linux.ibm.com>]

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.

The pattern of how the KMSG_COMPONENT is used was partially also used for
non s390 specific code, for whatever reasons.

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