vfs: Remove unnecessary list_for_each_entry_safe() from evict_inodes()

evict_inodes() uses list_for_each_entry_safe() to iterate sb->s_inodes
list. However, since we use i_lru list entry for our local temporary
list of inodes to destroy, the inode is guaranteed to stay in
sb->s_inodes list while we hold sb->s_inode_list_lock. So there is no
real need for safe iteration variant and we can use
list_for_each_entry() just fine.
