util: make calling remove_from_list multiple times in a row safe
This commit fixes an infinite loop in foreach_s if remove_from_list is used
more than once on the same item with other list operations in between.
NOTE: This is a candidate for the 7.9 branch because the commit
"r300g: fixup long-lived BO maps being incorrectly unmapped when flushing"
depends on it.
