Denis Bolotin eb62cca9be qed: Fix QM getters to always return a valid pq
The getter callers doesn't know the valid Physical Queues (PQ) values.
This patch makes sure that a valid PQ will always be returned.

The patch consists of 3 fixes:

 - When qed_init_qm_get_idx_from_flags() receives a disabled flag, it
   returned PQ 0, which can potentially be another function's pq. Verify
   that flag is enabled, otherwise return default start_pq.

 - When qed_init_qm_get_idx_from_flags() receives an unknown flag, it
   returned NULL and could lead to a segmentation fault. Return default
   start_pq instead.

 - A modulo operation was added to MCOS/VFS PQ getters to make sure the
   PQ returned is in range of the required flag.
