fs/9p: allow disable of xattr support on mount
xattr creates a lot of additional messages for 9p in
the current implementation. This allows users to
conditionalize xattr support on 9p mount if they
are on a connection with bad latency. Using this
flag is also useful when debugging other aspects
of 9p as it reduces the noise in the trace files.
