[PATCH] gssd: Fix allocated buffer size for the scraped acceptor name in do_downcall

[Veli-Matti Lintu <veli-matti.lintu@opinsys.fi>]

In commit 51fda07a "gssd: scrape the acceptor name out of the context"
the allocated buffer size is not large enough to hold the actual data
that is written to the buffer. This fixes the allocated buffer size.
