RDMA/core: Constify struct attribute_group
The only usage of the pma_table field in the ib_port struct is to pass its address to sysfs_create_group() and sysfs_remove_group(). Make it const to make it possible to constify a couple of static struct attribute_group. This allows the compiler to put them in read-only memory.
