dma-buf: don't hold the mutex around map/unmap calls
The mutex protects the attachment list and hence needs to be held
around the callbakc to the exporters (optional) attach/detach
functions.
Holding the mutex around the map/unmap calls doesn't protect any
dma_buf state. Exporters need to properly protect any of their own
state anyway (to protect against calls from their own interfaces).
So this only makes the locking messier (and lockdep easier to anger).
Therefore let's just drop this.
v2: Rebased on top of latest dma-buf-next git.
