Dmitry Kravkov 4293b9f57a bnx2x: Don't pretend during register dump 
As part of a register dump, the interface pretends to have the identity
of other interfaces of the same physical device in order to perform
HW configuration for them - specifically, it needs to prevent attentions
from generating on those functions as the register dump accesses registers
in common blocks which whose reading might generate an attention.

However, such pretension is unsafe - unlike other flows in which the driver
uses pretend, during register dump there is no guarantee no other HW access
will take place (by other flows). If such access will take place, the HW will
be accessed by the wrong interface, and leave both functions in an incorrect
state.

This patch removes all pretensions from the register dump flow. Instead, it
changes initial configuration of attentions such that no fatal attention will
be generated for other functions as a result of the register dump
(notice however, a debug print claiming an attention from other functions IS
possible during the register dump)

*
* IMPORTANT REMARKS:
* 1. the cmng_init struct does not represent the contiguous internal ram
* structure. the driver should use the XSTORM_CMNG_PERPORT_VARS_OFFSET
* offset in order to write the port sub struct and the
* PFID_FROM_PORT_AND_VNIC offset for writing the vnic sub struct (in other
* words - don't use memcpy!).
* 2. although the cmng_init struct is filled for the maximal vnic number
* possible, the driver should only write the valid vnics into the internal
* ram according to the appropriate port mode.
