IB/uverbs: Add IDRs array attribute type to ioctl() interface
Methods sometimes need to get a flexible set of IDRs and not a strict set
as can be achieved today by the conventional IDR attribute. Add a new
IDRS_ARRAY attribute to the generic uverbs ioctl layer.
IDRS_ARRAY points to array of idrs of the same object type and same access
rights, only write and read are supported.
