[PATCH] CLK: TI: DRA7: return error code in failure case

[Julia Lawall]

From: Julia Lawall <Julia.Lawall@xxxxxxx>

Add a returned error code in the MAX_APLL_WAIT_TRIES case.  Remove the
updating of the return variable r to 0 if MAX_APLL_WAIT_TRIES is not yet
reached, because r is already 0 at this point.
