bnx2x: fix ring size for 10G functions

Commit c4b86a2f23e0d2d1bb7f45d19c6aef8e69563a0a caused
1G functions to allocate rx rings which were 1/10 of the
size of 10G functions' rx rings.

However, it also caused 10G functions on 5771x boards to
allocate small rings, which limits their possible (default)
rx throughput. This patch causes all 10G functions to use
rings of intended length by default.
