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