common:dotlock: Escalate a warning message up to INFO from DEBUG.
* common/dotlock.c (dotlock_take): Use my_info_1 when already locked. (dotlock_release): Likewise.
Since recursive lock is not intended with dotlock (yet), it's a
programming error when detecting already locked state on the call of
dotlock_take. Also, it's a programming error when detecting
non-locked state on the call of dotlock_release. Use of my_debug_1 is
not relevant here.
