RDMA/qedr: fix QP's ack timeout configuration

		 *    "12.7.34 LOCAL ACK TIMEOUT

		 *    Value representing the transport (ACK) timeout for use by

		 *    the remote, expressed as: 4.096 * 2^timeout [usec]"

		 * The FW expects timeout in msec so we need to divide the usec

		 * result by 1000. We'll approximate 1000~2^10, and 4.096 ~ 2^2,

		 * so we get: 2^2 * 2^timeout / 2^10 = 2^(timeout - 8).

		 * The value of zero means infinite so we use a 'max_t' to make

		 * sure that sub 1 msec values will be configured as 1 msec.
