net/ncsi: Fix the multi thread manner of NCSI driver
Currently NCSI driver will send several NCSI commands back to back without
waiting the response of previous NCSI command or timeout in some state
when NIC have multi channel. This operation against the single thread
manner defined by NCSI SPEC(section 6.3.2.3 in DSP0222_1.1.1)
According to NCSI SPEC(section 6.2.13.1 in DSP0222_1.1.1), we should probe
one channel at a time by sending NCSI commands (Clear initial state, Get
version ID, Get capabilities...), than repeat this steps until the max
number of channels which we got from NCSI command (Get capabilities) has
been probed.
Fixes: e6f44ed6d04d ("net/ncsi: Package and channel management")
