[PATCH AUTOSEL 5.7 253/388] RDMA/efa: Fix setting of wrong bit in get/set_feature commands

From: Gal Pressman <galpress@amazon.com>

[ Upstream commit cc8a635e24acf2793605f243c913c51b8c3702ab ]

When using a control buffer the ctrl_data bit should be set in order to
indicate the control buffer address is valid, not ctrl_data_indirect
which is used when the control buffer itself is indirect.

Fixes: e9c6c5373088 ("RDMA/efa: Add common command handlers")
