Bluetooth: Mesh: Check the CID field before opcode compare

Bluetooth Mesh Vendor model hava company id field.

Accordin MeshPRFV1.0.1 3.7.3.1 Operation codes.

The 3-octet opcodes are used for manufacturer-specific opcodes.
The company identifiers are 16-bit values defined by the
Bluetooth SIG and are coded into the second and third octets of
the 3-octet opcodes.

Therefore, we can speed up the search process by checking whether
CID fields match, rather than comparing opcodes one by one.
