Jiang Liu c12de882e7 megaraid_sas: fix bug in handling return value of pci_enable_msix_range() 
Function pci_enable_msix_range() may return negative values for error
conditions. So it's a bug by checking (pci_enable_msix_range() != 0)
for success and causes failure to megaraid driver when MSI is disabled.
[   16.487267] megaraid_sas 0000:02:00.0: Controller type: iMR
[   16.487275] genirq: Flags mismatch irq 0. 00000000 (megasas) vs. 00015a00 (tii
mer)
[   16.487347] megasas: Failed to register IRQ for vector 0.
