Paul Chaignon e49e6f6db0 bpf, mips: Limit to 33 tail calls 
All BPF JIT compilers except RISC-V's and MIPS' enforce a 33-tail calls
limit at runtime.  In addition, a test was recently added, in tailcalls2,
to check this limit.

This patch updates the tail call limit in MIPS' JIT compiler to allow
33 tail calls.

Fixes: b6bd53f9c4 ("MIPS: Add missing file for eBPF JIT.")
