[PATCH] mtd: fix compile warnings

[Adam]

From: Adam-0320 <adam0320a at gmail.com>

ubi-mdeia.h defines 'struct ubi_vid_hdr'. It is used as a parameter type
of function 'ubigen_init_ec_hdr', which is declared in libubigen.h.
ubiformat.c and liubigen.c use this function. And they both have
included ubi-mdeia.h and libubigen.h. However, mtdinfo.c includes
libubigen.h but not ubi-mdeia.h. This also happens to 'ubi_ec_hdr'.
These issues lead to warnings:

In file included from ubi-utils/mtdinfo.c:34:
./include/libubigen.h:124:32: warning: 'struct ubi_ec_hdr' declared
inside parameter list will not be visible outside of this definition
or declaration
  124 |                         struct ubi_ec_hdr *hdr, long long ec);
      |                                ^~~~~~~~~~
./include/libubigen.h:140:33: warning: 'struct ubi_vid_hdr' declared
inside parameter list will not be visible outside of this definition
or declaration
  140 |                          struct ubi_vid_hdr *hdr, int lnum,
      |                                 ^~~~~~~~~~~

So include ubi-media.h in libubigen.h.
