ALSA: mixer_oss: Remove some incorrect kfree_const() usages

Browse source 
[ Upstream commit 368e4663c557de4a33f321b44e7eeec0a21b2e4e ]

"assigned" and "assigned->name" are allocated in snd_mixer_oss_proc_write()
using kmalloc() and kstrdup(), so there is no point in using kfree_const()
to free these resources.

Switch to the more standard kfree() to free these resources.

This could avoid a memory leak.
