In lx_hardware_open(), if lx_set_granularity() fails,
call lx_pipe_release() to release the resoueces.

Thanks for the patch. But beware that this isn't about the kernel
resource allocation or free, but rather the manipulation of the
chip-inside configuration. So there is no memory leak or such.
And, this doesn't look like the only place that leads to the
unbalanced / unexpected configuration, and we might need to address
all...
