When path is truncated by PATH_MAX limitation, it causes QEMU to access
incorrect file. So use original full path instead of PATH_MAX within
9pfs (need check/process ENOMEM for related memory allocation).
Also find/fix several another related issues when failure occurs.
- check 'fh' in handle_na
During the test, I found that if the path is long, the performance is
very very slow under 9pfs (whether apply this patch or not, the results
are the same).
So after this patch passes checking, I will/should analyse this
performance issue, next.
Thanks.
