SMB3: retry on STATUS_INSUFFICIENT_RESOURCES instead of failing write
Some servers such as Windows 10 will return STATUS_INSUFFICIENT_RESOURCES
as the number of simultaneous SMB3 requests grows (even though the client
has sufficient credits). Return EAGAIN on STATUS_INSUFFICIENT_RESOURCES
so that we can retry writes which fail with this status code.
This (for example) fixes large file copies to Windows 10 on fast networks.
