9p: remove unnecessary v9fses->options which duplicates the mount string

Browse Source 
The mount options string is saved in sb->s_options. This patch removes
the redundant duplicating of the mount options. Also, since we are not
displaying anything special in show options, we replace v9fs_show_options
with generic_show_options for now.
