Sending host information to shost_printk
prior to host initialization in fnic is unnecessary.
Replace shost_printk and a printk prior to this
initialization with pr_info and pr_err accordingly.

Please use 'dev_info' and 'dev_err' instead.
pr_info/pr_err have the problem that they don't reference
the device generating the message, making tracking of
related messages in a large message log problematic.

Cheers,

Hannes

Thanks for pointing this out. I'll incorporate this in the next version of changes.
