cifs: Pass unbyteswapped eof value into SMB2_set_eof()

Browse Source 
Change SMB2_set_eof() to take eof as CPU order rather than __le64 and pass
it directly rather than by pointer.  This moves the conversion down into
SMB_set_eof() rather than all of its callers and means we don't need to
undo it for the traceline.
