Subject: [PATCH 3.18 009/104] cifs: use correct format characters

[ Upstream commit 259594bea574e515a148171b5cd84ce5cbdc028a ]

When compiling with -Wformat, clang emits the following warnings:

fs/cifs/smb1ops.c:312:20: warning: format specifies type 'unsigned
short' but the argument has type 'unsigned int' [-Wformat]
                         tgt_total_cnt, total_in_tgt);
                                        ^~~~~~~~~~~~

fs/cifs/cifs_dfs_ref.c:289:4: warning: format specifies type 'short'
but the argument has type 'int' [-Wformat]
                 ref->flags, ref->server_type);
                 ^~~~~~~~~~

fs/cifs/cifs_dfs_ref.c:289:16: warning: format specifies type 'short'
but the argument has type 'int' [-Wformat]
                 ref->flags, ref->server_type);
                             ^~~~~~~~~~~~~~~~

fs/cifs/cifs_dfs_ref.c:291:4: warning: format specifies type 'short'
but the argument has type 'int' [-Wformat]
                 ref->ref_flag, ref->path_consumed);
                 ^~~~~~~~~~~~~

fs/cifs/cifs_dfs_ref.c:291:19: warning: format specifies type 'short'
but the argument has type 'int' [-Wformat]
                 ref->ref_flag, ref->path_consumed);
                                ^~~~~~~~~~~~~~~~~~
The types of these arguments are unconditionally defined, so this patch
updates the format character to the correct ones for ints and unsigned
ints.
