If match_fsid() returns -1 we shouldn't assume that the path definitely doesn't match the fsid, though it might not. This is a similar situation to where an export is expected to be a mount point, but is found not to be one. So it can be handled the same way, by setting 'dev_missing'. This will only have an effect is no other path matched the fsid, which is what we want. The current code results in nothing being exported and any export point, or any mount point beneath a crossmnt export point fail a 'stat' request, which is too harsh.
