ARM: net: bpf: avoid 'bx' instruction on non-Thumb capable CPUs
Avoid the 'bx' instruction on CPUs that have no support for Thumb and
thus do not implement this instruction by moving the generation of this
opcode to a separate function that selects between:
bx reg
and
mov pc, reg
according to the capabilities of the CPU.
Fixes: 39c13c204bb1 ("arm: eBPF JIT compiler")
