scsi: qedi: return via va_end to match corresponding va_start
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."
