lapdm: Allow SABM L=0 in Timer Recovery State
3GPP TS 44.006 8.6.3 "Procedures for re-establishment" is quite
explicit:
"""
When the data link layer receives in the multiple frame established state
or !!!timer recovery state!!! a DL-ESTABLISH- REQUEST primitive from layer
3 or an SABM (with L=0), the normal establishment procedure of sub-clause
8.4.1.2 shall be initiated.
"""
If L>0 in that state, send a DM as stated in 8.4.1.2:
"""
If the data link layer entity is unable to enter the multiple-frame-established
state, it shall respond to the SABM command with a DM response with the F bit
set to the same binary value as the P bit in the received SABM command.
"""
