ASoC: soc-core: fix RIP warning on card removal
SOF module load/unload tests show nasty recurring warnings:
WARNING: CPU: 5 PID: 1339 at sound/core/control.c:466
snd_ctl_remove+0xf0/0x100 [snd]
RIP: 0010:snd_ctl_remove+0xf0/0x100 [snd]
This regression was introduced by the removal of the call to
soc_remove_link_components() before soc_card_free() is invoked.
Go back to the initial order but only call
soc_remove_link_components() once.
