Subject: [PATCH] staging: lustre: lmv: add missing function declaration

We get 1 warning when building kernel with W=1:
drivers/staging/lustre/lustre/lmv/lmv_obd.c:2774:5: warning: no previous prototype for 'lmv_pack_md' [-Wmissing-prototypes]

In fact, this function is not declared in any file,but should be
declared in a header file, thus can be recognized in other file.

So this patch adds the declarations into
drivers/staging/lustre/lustre/include/lustre_lmv.h.
