Subject: scsi: libsas: move bus_reset_handler() to target_reset_handler()
Git-commit: cc199e78460565eeab0399875dbf9da8e2901c42
Patch-mainline: v4.14-rc1
References: bsc#1068693

The bus reset handler is calling I_T Nexus reset, which logically is a
target reset as it need to specify both the initiator and the target.
So move it to target reset.
