[PATCH] ALSA: asihpi: Simplify error handling in PCM substream setup

[Jihed Chaibi <jihed.chaibi.dev@gmail.com>]

Refactor error handling in the PCM substream setup to combine redundant
checks and improve code readability. Free the dpcm structure and return
appropriate error codes (-EBUSY for HPI_ERROR_OBJ_ALREADY_OPEN, -EIO
for other errors) in a single block.
