ALSA: firewire-lib: fix error codes for allocation failure
Return -ENOMEM if kcalloc() fails. Currently the code returns success.
Fixes: f9e5ecdfc2c2 ("ALSA: firewire-lib: add replay target to cache sequence of packet")
Fixes: 6f24bb8a157c ("ALSA: firewire-lib: pool sequence of packet in IT context independently")
