[Qemu-trivial] [PATCH 2/2] hw/9pfs: Supply missing va_end()

[Markus Armbruster]

C99 7.15.1: Each invocation of the va_start and va_copy macros shall
be matched by a corresponding invocation of the va_end macro in the
same function.

Spotted by Coverity.  Harmless on the (common) systems where va_end()
does nothing.
