DO NOT MERGE ANYWHERE Fix double mutex unlock and if() condition

Commit "L2CAP and SDP Search API for BT profiles (2/2)" introduced two
separate issues in btsock_rfc_signaled():

1. The "slot_lock" potentially gets unlocked twice, causing
   undefined behaviour.

2. The call to BTA_JvRfcommWrite() was incorrectly taken outside
   of the conditional if() block that only executes the code if
   data is available.

This patch reverts the relevant locking change and fixes the if()
condition.
