ALSA: ymfpci: Create card with device-managed snd_devm_card_new()

[ Upstream commit f33fc1576757741479452255132d6e3aaf558ffe ]

snd_card_ymfpci_remove() was removed in commit c6e6bb5eab74 ("ALSA:
ymfpci: Allocate resources with device-managed APIs"), but the call to
snd_card_new() was not replaced with snd_devm_card_new().

Since there was no longer a call to snd_card_free, unloading the module
would eventually result in Oops:
