[PATCH] ata: pata_hpt3x2n: prevent potential forever loop in hpt3xn_calibrate_dpll()

[Dan Carpenter <error27@xxxxxxxxx>]

This code accidentally reuses "tries" as the iterator for both the inside
and outside loops.  It means that the potentially the "tries" could be
reset to 0x1000 and never reach 0x5000.

Fixes: 669a5db411d8 ("[libata] Add a bunch of PATA drivers.")
