smb: client: call smbd_destroy() in the same splace as kernel_sock_shutdown()/sock_release()

With commit b0432201a11b ("smb: client: let destroy_mr_list() keep
smbdirect_mr_io memory if registered") the changes from commit
214bab448476 ("cifs: Call MID callback before destroying transport") and
commit 1d2a4f57cebd ("cifs:smbd When reconnecting to server, call
smbd_destroy() after all MIDs have been called") are no longer needed.

And it's better to use the same logic flow, so that
the chance of smbdirect related problems is smaller.

Fixes: 214bab448476 ("cifs: Call MID callback before destroying transport")
Fixes: 1d2a4f57cebd ("cifs:smbd When reconnecting to server, call smbd_destroy() after all MIDs have been called")
