[PATCH] dma-buf: fix comment in dma_buf_llseek to match implementation

The comment in dma_buf_llseek() referenced a "SEEK_END(0), SEEK_CUR(0)
pattern", but the implementation does not support SEEK_CUR - it only
handles SEEK_END and SEEK_SET, returning -EINVAL for anything else.

Replace SEEK_CUR with SEEK_SET in the comment so that it accurately
describes the supported idiomatic pattern.
