nvmet: add support for the Write Zeroes command Add support for handling write zeroes command on target. Call into __blkdev_issue_zeroout, which the block layer expands into the best suitable variant of zeroing the LBAs. Allow write zeroes operation to deallocate the LBAs when calling __blkdev_issue_zeroout.
