ASoC: Intel: Atom: sst_loader: remove always-true condition

Fix cppcheck warning:

sound/soc/intel/atom/sst/sst_loader.c:401:43: style: Redundant
condition: If 'EXPR == 4', the comparison 'EXPR != 3' is always
true. [redundantCondition]

 if (sst_drv_ctx->sst_state !=  SST_RESET ||
                                          ^

In this case, if sst_state == SST_SHUTDOWN then the first test is
already true. 2014 bug, yay.
