Subject: [PATCH v2] Bluetooth: hci_qca: Remove redundant initializations to zero

The qca_data structure is allocated with kzalloc() and hence
zero-initialized. Remove a bunch of unnecessary explicit
initializations of struct members to zero.

just noticed that this patch fell through the cracks, resending a
rebased version.

Changes in v2:
- added 'Reviewed-by' tag from Balakrishna
- rebased on bluetooth-next/master
