Bluetooth: Replace constant hw_variant from Intel Bluetooth firmware filename
The format of Intel Bluetooth firmware filename for bootloader product
is ibt-<hw_variant>-<device_revision_id>.sfi
Currently the driver uses a constant value 11 (0x0b) for hw_variant
to support LnP/SfP product. But new product like WsP product has
a different value such as 12 (0x0c).
To support the multiple products, this patch replaces the constant
value of hw_variant to the actual hw_variant value read from
the device.
