[PATCH] v9fs: return the correct error when interrupted by signal

[Latchesar Ionkov <lucho@ionkov.net>]

If a signal interrupts the user process, v9fs sends a flush request to the
file server and waits for its response. It error code is incorrectly set to
the error code of the flush message instead of ERESTARTSYS. The patch sets
the error code to the correct value.
