SMB: Processes do not exit when accessing an unresponsive SMB server

Issue

• Processes accessing a SMBv1.0 share never exit even though soft is a mount option instead they go into a sleep state and can be killed.
• Previously, the process would exit on its own within 120 seconds
• Processes accessing a SMBv2/3 share exit the first time, but subsequently never exit when accessed a second time. The process goes into a sleep state and can be killed.
• Previously, the process would exit within 10 seconds.
• Should the SMB client reconnect to the SMB server, the existing running process will go into "D" state and can not be killed.
