Subject: [PATCH] scsi: megaraid_sas: Use synchronize_irq in target reset case
References: bsc#1049528,FATE#322937
Git-commit: bdb5c55fffb9cb11ca7053ffc2d076aa70bf4aac
Patch-Mainline: v4.14-rc1
Similar to task abort case, use synchronize_irq API in target reset
case. Also, remove redundant call to megasas_complete_cmd_dpc_fusion
after calling megasas_sync_irqs in task abort case.
