tracefs: Fix inode allocation

BugLink: https://bugs.launchpad.net/bugs/2083656

commit 0df2ac59bebfac221463ef57ed3554899b41d75f upstream.

The leading comment above alloc_inode_sb() is pretty explicit about it:

  /*
   * This must be used for allocating filesystems specific inodes to set
   * up the inode reclaim context correctly.
   */

Switch tracefs over to alloc_inode_sb() to make sure inodes are properly
linked.
