libcephfs: repeatedly use new default_perms instead of pick_my_perms()

There's no need to invoke it each time for library-using clients. Either they've
set the default uid/gid or they haven't, and they aren't going to be switching
dynamic uid/gid a bunch either. (Right? Anyway, we want them to use the
not-here-yet functions specifying uid/gid on each call.)
