smb client may use large read/write when it should not
The SMB client has some code that computes when it may use "large read/write" which predated clarifications in the MS-SMB spec. about when that capability should be used. See:
Since then, MS-SMB 18.104.22.168 has clarified that when SMB signing is enabled, the client should NOT use "large read/write" even though the server might offer those capabilities.
The current code disables large read/write with signing if the server looks like a Windows system, but that part of the check (is this windows) should be removed, so that the client always disables large read/write when signing is in use.
