mpt3sas: Manage MSI-X vectors according to HBA device type

1. Do not enable MSI-X vectors for SAS2008 B0 controllers

2. Enable a single MSI-X vector for the following controller:

   a. SAS2004
   b. SAS2008
   c. SAS2008_1
   d. SAS2008_2
   e. SAS2008_3
   f. SAS2116_1
   g. SAS2116_2

3. Enable Combined Reply Post Queue Support (i.e. 96 MSI-X vectors)
   for Gen3 Invader/Fury C0 and above revision HBAs

4. Enable Combined Reply Post Queue Support (i.e. 96 MSI-X vectors)
   for all Intruder and Cutlass HBAs
