ocfs2: remove kfree() redundant null checks
smatch analysis indicates a number of redundant NULL checks before
calling kfree(), eg:
fs/ocfs2/alloc.c:6138 ocfs2_begin_truncate_log_recovery() info:
redundant null check on *tl_copy calling kfree()
fs/ocfs2/alloc.c:6755 ocfs2_zero_range_for_truncate() info:
redundant null check on pages calling kfree()
etc....
