ALSA: seq: Fix snd_seq_call_port_info_ioctl in compat mode
This reverts one hunk of commit ef44a1ec ("ALSA: sound/core: use memdup_user()"), which replaced a number of kmalloc followed by memcpy with memdup calls. In this case, we are copying from a struct snd_seq_port_info32 to a struct snd_seq_port_info, but the latter is 4 bytes longer than the 32-bit version, so we need to separate kmalloc and copy calls.
