Jaegeuk Kim 33b1395124 f2fs: use dget_parent and file_dentry in f2fs_file_open ...

This patch synced with the below two ext4 crypto fixes together.

In 4.6-rc1, f2fs newly introduced accessing f_path.dentry which crashes
overlayfs. To fix, now we need to use file_dentry() to access that field.

Fixes: c0a37d4878 ("ext4: use file_dentry()")
Fixes: 9dd78d8c9a ("ext4: use dget_parent() in ext4_file_open()")
