media: rzv2h-ivc: Fix concurrent buffer list access<\/p>\n
The list of buffers (`rzv2h_ivc::buffers.queue`) is protected by a
\nspinlock (`rzv2h_ivc::buffers.lock`). However, in
\n`rzv2h_ivc_transfer_buffer()`, which runs in a separate workqueue, the
\n`list_del()` call is executed without holding the spinlock, which makes
\nit possible for the list to be concurrently modified<\/p>\n
Fix that by removing a buffer from the list in the lock protected section.<\/p>\n
