kconfig: update compression algorithm info
There have been new compression algorithms added without updating nearby relevant descriptive text that refers to (a) the number of compression algorithms and (b) the most recent one. Fix these inconsistencies. Signed-off-by: Randy Dunlap <[email protected]> Reported-by: <[email protected]> Cc: Lasse Collin <[email protected]> Cc: "H.
