file-posix: fix max_iov for /dev/sg devices
Git-commit: 8ad5ab6148dca8aad297c134c09c84b0b92d45ed
References: bsc#1190425
Even though it was only called for devices that have bs->sg set (which
must be character devices), sg_get_max_segments looked at /sys/dev/block
which only works for block devices.
On Linux the sg driver has its own way to provide the maximum number of
iovecs in a scatter/gather list, so add support for it. The block device
path is kept because it will be reinstated in the next patches.
