scsi: Always define blogic_pci_tbl structure

The blogic_pci_tbl structure is used by the MODULE_DEVICE_TABLE macro.
There is no longer a need to protect it with the MODULE condition, since
this no longer causes the compiler to warn about an unused variable.

To avoid warnings when -Wunused-const-variable option is used, mark it
as __maybe_unused for such configuration.
