6e1bba7430 fix(i2c_master): fix deadlock on s_i2c_transaction_start failure 
As pointed out in PR #13134 by @MatthiasKunnen, there is a deadlock in
`s_i2c_synchronous_transaction()` if `s_i2c_transaction_start()` should fail
because, on error, s_i2c_synchronous_transaction() returns before releasing the
lock.

This commit fixes the deadlock without any other changes.

Closes: #13387
