Karsten Graul 82060d9311 net/smc: do not wait under send_lock
[ Upstream commit 33f3fcc290 ]

smc_cdc_get_free_slot() might wait for free transfer buffers when using
SMC-R. This wait should not be done under the send_lock, which is a
spin_lock. This fixes a cpu loop in parallel threads waiting for the
send_lock.
