s390/ap: rename and clarify ap state machine related stuff
There is a state machine held for each ap queue device. The states and functions related to this where somethimes noted with _sm_ somethimes without. This patch clarifies and renames all the ap queue state machine related functions, enums and defines to have a _sm_ in the name. There is no functional change coming with this patch - it's only beautifying code. Signed-off-by: Harald Freudenberger <freude@linux.ibm.com> Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>
