media: v4l: async: Fix duplicated list deletion
The list deletion call dropped here is already called from the
helper function in the line before. Having a second list_del()
call results in either a warning (with CONFIG_DEBUG_LIST=y):
list_del corruption, c46c8198->next is LIST_POISON1 (00000100)
If CONFIG_DEBUG_LIST is disabled the operation results in a
kernel error due to NULL pointer dereference.
Fixes: 28a1295795d8 ("media: v4l: async: Allow multiple connections between entities")
