i2c: cadence: Remove redundant expression in if clause

In the mrecv() function the Cadence I2C driver has the following expression
in an if clause.

	((id->p_msg->flags & I2C_M_RECV_LEN) != I2C_M_RECV_LEN) &&
	 (id->recv_count <= CDNS_I2C_FIFO_DEPTH))

Earlier in the same function when I2C_M_RECV_LEN is set the recv_count is
initialized to a value that is larger than CDNS_I2C_FIFO_DEPTH. This means
if the first expression is false the second expression is also false.
Checking the first expression is thus redundant and can be removed.

This slightly simplifies the logic.
