Subject: [PATCH][rds-next] rds: make functions rds_info_from_znotifier and rds_message_zcopy_from_user static

From: Colin Ian King <colin.king@...onical.com>

Functions rds_info_from_znotifier and rds_message_zcopy_from_user are
local to the source and do not need to be in global scope, so make them
static.

Cleans up sparse warnins:
net/rds/message.c:70:27: warning: symbol 'rds_info_from_znotifier' was
not declared. Should it be static?
net/rds/message.c:358:5: warning: symbol 'rds_message_zcopy_from_user'
was not declared. Should it be static?
