Fixes in registers dump:
        - Properly calculate dump length for 57712.
        - Prevent HW blocks parity attentions when dumping registers in order to
prevent false parity errors handling.
        - Update the bnx2x_dump.h file: old one had a few bugs that could cause
fatal HW error as a result of a registers dump.
