lapd_core: Fix MDL-ERROR ind after RELEASE ind

in lapd_t200_cb() The RELEASE INDICATION is transmitted before
the MDL ERROR INIDCATION, this prevents the MDL ERROR INDICATION
from being sent because the RELASE INDICATION close to connection
eraly. This commit puts the messages into the correct order.
