Brett Creeley 2e05de2305 ionic: Don't send reset commands if FW isn't running ...

[ Upstream commit b8fd0271dad00b953caaabe73474788d3d19e252 ]

It's possible the FW is already shutting down while the driver is being
removed and/or when the driver is going through reset. This can cause
unexpected/unnecessary errors to be printed:

eth0: DEV_CMD IONIC_CMD_PORT_RESET (12) error, IONIC_RC_ERROR (29) failed
eth1: DEV_CMD IONIC_CMD_RESET (3) error, IONIC_RC_ERROR (29) failed

Fix this by checking the FW status register before issuing the reset
commands.

Also, since err may not be assigned in ionic_port_reset(), assign it a
default value of 0, and remove an unnecessary log message.
