[LTP] [PATCH] bugfix for block_dev_kernel/ltp_block_dev.c

[dongshijiang]

Add genhd.h and blkdev.h to ltp_block_dev.c.

Failed at compile time on kernel 5.12 due to change of register_blkdev function definition from linux/fs.h to linux/genhd.h and failure of test case tc05,The reason is that the BLKDEV_MAJOR_MAX definition was changed from fs.h to blkdev.h
