[ Upstream commit b8e3130dd96b7b2d6d92e62dcd1515af30212fe2 ]
Since a while now the uverbs layer checks if the driver implements a
function before allowing the ucmd to proceed. This largely obsoletes the
cmd_mask stuff, but there is some tricky bits in drivers preventing it
from being removed.
Remove the easy elements of uverbs_ex_cmd_mask by pre-setting them in the
core code. These are triggered soley based on the related ops function
pointer.
query_device_ex is not triggered based on an op, but all drivers already
implement something compatible with the extension, so enable it globally
too.
