copy_from_sockptr() helper is unsafe, unless callers
did the prior check against user provided optlen.
Too many callers get this wrong, lets add a helper to
fix them and avoid future copy/paste bugs.

[BUG]
There is a recent report that when memory pressure is high (including
cached pages), btrfs can spend most of its time on memory allocation in
btrfs_alloc_page_array() for compressed read/write.
