Bluetooth: btmtkuart: fix recv_buf() return value
[ Upstream commit 64057f051f20c2a2184b9db7f8037d928d68a4f4 ]
Serdev recv_buf() callback is supposed to return the amount of bytes
consumed, therefore an int in between 0 and count.
Do not return negative number in case of issue, just print an error and
return count. This fixes a WARN in ttyport_receive_buf().
