SMBv2 share returns "Resource temporarily unavailable" when reconnecting to expired or deleted session

Issue

• RHEL7 clients now reconnect to a SMBv2 session after it is expired or deleted returning Resource temporarily unavailable.
• However, the SMB client receives EAGAIN (Resource temporarily unavailable), instead of transparently recovering when accessing the SMB share via stat or ls when requesting up-to-date inode information.
• Depending on an application's activity during reconnect, no error may be returned (i.e. write request).
