[PATCH] dma-buf: docs: remove invalid struct member

["Nicolás Antinori" <nico.antinori.7@gmail.com>]

In the structs dma_fence_array and dma_fence_chain, the field 'lock'
has been removed, but its documentation comment remained. Remove the
stale descriptions to clear up the following kernel-doc warnings:

WARNING: ./include/linux/dma-fence-array.h:47 Excess struct member 'lock' description in 'dma_fence_array'
WARNING: ./include/linux/dma-fence-array.h:47 Excess struct member 'lock' description in 'dma_fence_array'
WARNING: ./include/linux/dma-fence-chain.h:48 Excess struct member 'lock' description in 'dma_fence_chain'
WARNING: ./include/linux/dma-fence-chain.h:48 Excess struct member 'lock' description in 'dma_fence_chain'

Fixes: 5943243914b9 ("dma-buf: use inline lock for the dma-fence-array")
Fixes: a408c0ca0c41 ("dma-buf: use inline lock for the dma-fence-chain")
