[PATCH 1/2] ALSA: compress: Use EOPNOTSUPP for missing pointer callbacks

["Cássio Gabriel" <cassiogabrielcontato@gmail.com>]

snd_compr_update_tstamp() returns a sentinel error when a
compress driver does not implement the pointer() callback.

Use -EOPNOTSUPP for that case instead of -ENOTSUPP. This
keeps the behavior the same while switching to the standard
unsupported-operation errno and avoids the checkpatch warning
about ENOTSUPP not being a SUSv4 error code.
