Bluetooth: Prefer sizeof(*ptr) when allocating memory
It's safer practice to use sizeof(*ptr) instead of sizeof(ptr_type) when
allocating memory in case the type changes. This also fixes the
following style of warnings from static analyzers:
CHECK: Prefer kzalloc(sizeof(*ie)...) over kzalloc(sizeof(struct inquiry_entry)...)
+ ie = kzalloc(sizeof(struct inquiry_entry), GFP_KERNEL);
