Fix bug #8005 - smbtorture4 BASE-TCONDEV fails when tested on Samba
When pulling non-aligned ucs2 strings, we neglected to add in the
pad byte to the buffer length we've eaten. This caused the device
string in TCONX (which seems to be one of the few places that uses
non-aligned ucs2 strings) to be incorrectly read.
Volker please check.
Jeremy.
