[PATCH] block/qcow2-bitmap: Add missing cast to silent GCC error |

Commit d1258dd0c8 ("qcow2: autoloading dirty bitmaps") added the
set_readonly_helper() GFunc handler, correctly casting the gpointer
user_data in both the g_slist_foreach() caller and the handler.
Few commits later (commit 1b6b0562db), the handler is reused in
qcow2_reopen_bitmaps_rw() but missing the gpointer cast, resulting
in the following error when using Homebrew GCC 12.2.0:
[2/658] Compiling C object libblock.fa.p/block_qcow2-bitmap.c.o
../../block/qcow2-bitmap.c: In function 'qcow2_reopen_bitmaps_rw':
../../block/qcow2-bitmap.c:1211:60: error: incompatible type for argument 3
of 'g_slist_foreach'
1211 | g_slist_foreach(ro_dirty_bitmaps, set_readonly_helper, false);
