[PATCH 5.3 102/180] ALSA: oxfw: fix return value in error path of isochronous resources reservation

[Greg Kroah-Hartman]

From: Takashi Sakamoto <o-takashi@xxxxxxxxxxxxx>

commit 59a126aa3113fc23f03fedcafe3705f1de5aff50 upstream.

Even if isochronous resources reservation fails, error code doesn't return
in pcm.hw_params callback.
