fio: make the ctrlr send keep alive in time

Browse Source 
In spdk_fio_setup when the connections are too many,
for example 16 subsystems, it would take too much time to
complete the probe. And it takes the mutex that makes the
poll_ctrlr function can't send the keep alive cmd which
causes the target timeout. Split the mutex so the poll_ctrlr
has the chance to sent keep alive.

Fixes issue: #1286
