[PATCH] efi_loader: file: set a backend block device for file operations

[AKASHI Takahiro]

In the current implementation, set_blk_dev() is called in opening a file,
but not in opening a directory. This will cause failures at succeeding
directory operations as the "current" block device remains nullified.
Adding set_blk_dev() fixes this issue.
