Call echo service immediately after socket reconnect
[ Upstream commit b8c600120fc87d53642476f48c8055b38d6e14c7 ]
Commit 4fcd1813e640 ("Fix reconnect to not defer smb3 session reconnect
long after socket reconnect") changes the behaviour of the SMB2 echo
service and causes it to renegotiate after a socket reconnect. However
under default settings, the echo service could take up to 120 seconds to
be scheduled.
The patch forces the echo service to be called immediately resulting a
negotiate call being made immediately on reconnect.
