Subject: spufs: Remove spurious WARN_ON for spu_deactivate for NOSCHED contexts

From: Jeremy Kerr <jk@ozlabs.org>
Commit 6cbf93960e64f313f6e247cbca7afaa50e3ee2c added a WARN_ON for
calling spu_deactivate on context created with the SPU_CREATE_NOSCHED
flag. However, all NOSCHED contexts will need to be deactivated when
the context is closed, so this gives a spurious warning when any
NOSCHED context is closed.

This change removes the WARN_ON.
