sfxge: fix overflow queue freeze
If TxQ lock is obtained, deferred packet list shold be serviced even if
the packet addition fails because of overflow.
Without the patch freeze happens if:
- queue is not blocked (i.e. completion does not trigger unblock and service)
- put-list overflow (1024 entries)
- sfxge_tx_packet_add() acquires TxQ lock just as it is released it in
sfxge_tx_qdpl_service() on the second CPU but before pending check
- sfxge_tx_packet_add() swizzles put-list to get-list, fails because of
non-tcp get-list overflow and returns without packet list service
- sfxge_tx_qdpl_service() on the second CPU checks that there are no
pending packets in the put-list and returns
Other possible solution is to guaranee that maximum length of the put-list
is less than maximum length of any get-list.

In an attempt to improve performance, cp reordered directories first

The sorting reorders multiple arguments passed to cp, which may be
undesirable.
Additionally, the comparison function does not induce a total order. Per
POSIX, this causes undefined behaviour in qsort().
NetBSD removed the sorting in 2009.
On filesystems that return directory entries in hash/btree order, sorting by
d_fileno before statting improves performance on large directories. However,
