i40e: Implement debug macro hw_dbg using dev_dbg
There are several uses of hw_dbg in the code, producing no output. This
patch implements it using dev_debug.
Initially the intention was to implement it using netdev_dbg, analogously
to what is done in ixgbe for instance. That approach was avoided due to
some early usages of hw_dbg, like i40e_pf_reset, before the VSI structure
initialization causing NULL pointer dereference during the driver probe if
the debug messages were turned on as soon as the module is probed.
v2:
- Use dev_dbg instead of pr_debug, and take advantage of dev_name
instead of crafting pretty much the same device name locally as suggested
by Jakub Kicinski.
