[BNX2]: Restructure RX ring init. code.

Factor out the common functions that will be used to initialize the
normal RX rings and the page rings.

Change the copybreak constant RX_COPY_THRESH to 128.  This same
constant will be used for the max. size of the linear SKB when pages
are used.  Copybreak will be turned off when pages are used.
