[PATCH v4 1/4] xfs_io: Disable -V if pwritev is not available

[Goldwyn Rodrigues <rgoldwyn@suse.de>]

From: Goldwyn Rodrigues <rgoldwyn@suse.com>

This results in default case which will display the error message
that command is not found. This is required for xfs_io builds which
did not support pwritev and an attempt is made to use -V.
