debugfs: fix placement of EXPORT_SYMBOL_GPL for debugfs_create_str()

The EXPORT_SYMBOL_GPL() for debugfs_create_str was placed incorrectly
away from the function definition. Move it immediately below the
debugfs_create_str() function where it belongs.

Fixes: d60b59b96795 ("debugfs: Export debugfs_create_str symbol")
