media: dvb-usb: m920x: Fix a potential memory leak in m920x_i2c_xfer()
In the Linux kernel, the following vulnerability has been resolved: media: dvb-usb: m920x: Fix a potential memory leak in m920x_i2c_xfer() 'read' is freed when it is known to be NULL, but not when a read error occurs. Revert the logic to avoid a small leak, should a m920x_read() call fail.
