ASoC: mediatek: mt8195: optimize property formatting error handling by using scnprintf()

Replace snprintf() with scnprintf() when constructing the property
and remove negative return error handling as scnprintf() returns the
actual number of bytes written to buffer.

snprintf() as defined by the C99 standard,returns the number of
characters that *would have been* written if enough space were
available.Use scnprintf() that returns the actual number of
characters written.
