cnic,bnx2i,bnx2fc: Fix inconsistent use of page size
The bnx2/bnx2x rings are made up of linked pages. However there is an upper limit on the page size as some the page size settings are 16-bit in the hardware/firmware interface. In the current code, some parts use BNX2_PAGE_SIZE which has a 16K upper limit and some parts use PAGE_SIZE. On archs with >= 64K PAGE_SIZE, it generates some compile warnings. Define a new CNIC_PAGE_SZIE which has an upper limit of 16K and use it consistently in all relevant parts.
