[SCSI] megaraid_sas: fixes for few endianess issues
Fixed two issues in this patch-
1) In function megasas_get_pd_list(), data read(pd_addr->deviceId) from DMAed memory is converted to CPU's endianess.
2) While register AEN, removed some endianness conversion on some fields, since their endianess is already converted.
