smb: client: move some params to cifs_open_info_data
Instead of passing @adjust_tz and some reparse point related fields as
parameters in ->query_path_info() and
{smb311_posix,cifs}_info_to_fattr() calls, move them to
cifs_open_info_data structure as they can be easily accessed through
@data.
No functional changes.
