[PATCH 04/97] megasas: fix mapped frame size |

From: Peter Lieven <address@hidden>
the current value of 1024 bytes (16 * MFI_FRAME_SIZE) we map is not enough to
hold
the maximum number of scatter gather elements we advertise. We actually need a
maximum of 2048 bytes. This is 128 max sg elements * 16 bytes (sizeof (union
mfi_sgl)).
