qnx6: Convert qnx6_find_entry() to qnx6_find_ino()

Browse Source 
It's hard to return a directory entry from qnx6_find_entry()
because it might be a long dir_entry with a different format.
So stick with the convention of returning an inode number,
but rename it to qnx6_find_ino() to reflect what it actually does,
and move the call to qnx6_put_page() inside the function which
lets us get rid of the res_page parameter.
