staging: most: video: fix potential race in list iteration

There is a pattern in the loops where the lock is dropped
to call a specific function and then re-acquired.

The list can be exposed during this short gap, creating a potential
race condition. This patch fixes the problem by replacing the list
head with a local free list using list_replace_init(), instead of
using the lock/unlock pattern in the loop.
