[PATCH v3 06/23] migration/hmp-cmds: Include 'block/block-global-state.h' header

["Philippe Mathieu-Daudé" <philmd@oss.qualcomm.com>]

migration-hmp-cmds.c uses types / methods declared in
"block/block-global-state.h".  Include the latter otherwise
we get when refactoring unrelated headers:

  ../migration/migration-hmp-cmds.c:911:5: error: use of undeclared identifier 'BdrvNextIterator'
    911 |     BdrvNextIterator it;
        |     ^
  ../migration/migration-hmp-cmds.c:918:15: error: call to undeclared function 'bdrv_first'
    918 |     for (bs = bdrv_first(&it); bs; bs = bdrv_next(&it)) {
        |               ^
