fs_parse: get rid of ->enums
Don't do a single array; attach them to fsparam_enum() entry instead. And don't bother trying to embed the names into those - it actually loses memory, with no real speedup worth mentioning. Simplifies validation as well. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
