LoongArch: BPF: Remove dead move_imm() call in BPF_NEG path

The BPF_NEG operation is a unary operator that performs `dst = -dst`.
The current code unconditionally executes a move_imm() call before the
subtraction, generating useless JITted instructions to load data into
the temporary register `t1`. This `t1` register is never used anywhere
else in the entire BPF_NEG path.

Remove this dead `move_imm()` call to avoid useless instructions.
