[PATCH] scsi: qedi: return via va_end to match corresponding va_start

[Colin King]

From: Colin Ian King <colin.k...@canonical.com>

Although on most systems va_end is a no-op, it is good practice
to use va_end on the function return path, especially since the
va_start documenation states:

  "Each invocation of va_start() must be matched by a corresponding
   invocation of va_end() in the same function."
