mpt2sas: annotate ioc->reply_post_host_index as __iomem
The MPT2SAS_ADAPTER reply_post_host_index[] holds calculated addresses
in memory mapped register space. Add an "__iomem" annotation to silence
the following sparse warnings:
drivers/scsi/mpt2sas/mpt2sas_base.c:1006:43:
warning: incorrect type in argument 2 (different address spaces)
expected void volatile [noderef] <asn:2>*addr
got unsigned long long [usertype] *<noident>
drivers/scsi/mpt2sas/mpt2sas_base.c:4299:22:
warning: cast removes address space of expression
drivers/scsi/mpt2sas/mpt2sas_base.c:4303:27:
