Hsin-Yu Chao 9e7e2b9eb1 Bluetooth: Add SCO fallback for invalid LMP parameters error 
[ Upstream commit 56b5453a86203a44726f523b4133c1feca49ce7c ]

Bluetooth PTS test case HFP/AG/ACC/BI-12-I accepts SCO connection
with invalid parameter at the first SCO request expecting AG to
attempt another SCO request with the use of "safe settings" for
given codec, base on section 5.7.1.2 of HFP 1.7 specification.

This patch addresses it by adding "Invalid LMP Parameters" (0x1e)
to the SCO fallback case. Verified with below log:
