mpt2sas: correct scsi_{target,device} hostdata allocation
In _scsih_{slave,target}_alloc, an incorrect structure type is passed
to sizeof() when allocating storage for hostdata. Luckily larger
structure types were used, so at least the wrong sizes were safe:
struct scsi_device (1784 bytes) > struct MPT2SAS_DEVICE (24 bytes)
struct scsi_target (760 bytes) > struct MPT2SAS_TARGET (40 bytes)
This fixes the following smatch warnings:
drivers/scsi/mpt2sas/mpt2sas_scsih.c:1295 _scsih_target_alloc()
warn: struct type mismatch 'MPT2SAS_TARGET vs scsi_target'
drivers/scsi/mpt2sas/mpt2sas_scsih.c:1409 _scsih_slave_alloc()
warn: struct type mismatch 'MPT2SAS_DEVICE vs scsi_device'
