[SCSI] ipr: fix a register read to use the correct address for 64 bit adapters
Fix ipr_reset_enable_ioa() to read the correct IOA to host interrupt register address for 64 bit adapters. We need to read the lower 32 bits, not the upper 32 bits. Also change the write of the 64 bit mask value to a single writeq instead of two writel calls. Finally, use the correct u8 type for the type field in the ipr_resource_entry structure.
