[PATCH v3] Bluetooth: Use kzalloc instead of kmalloc/memset

[PATCH v3] Bluetooth: Use kzalloc instead of kmalloc/memset

[Kang Minchul]

Replace kmalloc+memset by kzalloc
for better readability and simplicity.

This addresses the cocci warning below:

WARNING: kzalloc should be used for d, instead of kmalloc/memset
