dpll: fix clock quality level reporting

The DPLL_CLOCK_QUALITY_LEVEL_ITU_OPT1_EPRC is not reported via netlink
due to bug in dpll_msg_add_clock_quality_level(). The usage of
DPLL_CLOCK_QUALITY_LEVEL_MAX for both DECLARE_BITMAP() and
for_each_set_bit() is not correct because these macros requires bitmap
size and not the highest valid bit in the bitmap.

Use correct bitmap size to fix this issue.
