[PATCH] fuse: BUG_ON's correction in fuse_dev_splice_write()

[Vasily Averin <vvs@virtuozzo.com>]

commit 963545357202 ("fuse: reduce allocation size for splice_write")
changed size of bufs array, so first BUG_ON should be corrected too.
Second BUG_ON become useless, first one also includes the second check:
any unsigned nbuf value cannot be less than 0.
