Fix committed to stress-ng:

FIBMAP on a block device is plainly wrong, it should only be applied to
a file. The FIBMAP ioctl to a scsi block device is the same as the
SCSI_IOCTL_SEND_COMMAND ioctl that requires a scsi_ioctl_command struct.
As it stands, we are passing an int with stack garbage as this struct
which is passing garbage to the ioctl. The deprecated SCSI ioctl creates
a scsi_request from the garbage and this causes the kernel to correctly
warn with a usercopy_abort that the structure is bogos. Fix this by not
calling FIBMAP on a raw SCSI device.
