pf->msg_enable is a bitmask, therefore assigning the value of the
"debug" parameter is wrong. It is initialized again later in
i40e_sw_init() so it didn't cause any problem, except that we missed
early debug messages. Moved the initialization and assigned
pf->hw.debug_mask the bitmask as that's what the driver actually uses
in i40e_debug(). Otherwise the debug parameter is just a noop.
Fixes: 5b5faa4 ("i40e: enable debug earlier")
