crypto: qat - fix default value of WDT timer
The QAT HW supports an hardware mechanism to detect an accelerator hang.
The reporting of a hang occurs after a watchdog timer (WDT) expires.
The value of the WDT set previously was too small and was causing false
positives.
Change the default value of the WDT to 0x7000000ULL to avoid this.
