Subject: [PATCH] dma-buf: Fix __dma_buf_debugfs_list_del argument for !CONFIG_DEBUG_FS

The arguments for __dma_buf_debugfs_list_del do not match for both the
CONFIG_DEBUG_FS case and the !CONFIG_DEBUG_FS case. The !CONFIG_DEBUG_FS
case should take a struct dma_buf *, but it's currently struct file *.
This can lead to the build error:

error: passing argument 1 of ‘__dma_buf_debugfs_list_del’ from
incompatible pointer type [-Werror=incompatible-pointer-types]

dma-buf.c:63:53: note: expected ‘struct file *’ but argument is of
type ‘struct dma_buf *’
   63 | static void __dma_buf_debugfs_list_del(struct file *file)

Fixes: bfc7bc539392 ("dma-buf: Do not build debugfs related code when !CONFIG_DEBUG_FS")
