Subject: Fix TightCompressionControl definition for big-endian
References: bsc#1171344
Upstream: merged
Git-commit: b487e58a4f8d0b879d34cb9be18a292c753daf3e

Bitfields are allocated from the most significant bit down to the
least significant bit on big-endian systems, so the declaration
order must be reversed to match on-wire format.
