fix: block: remove the error argument to the block_bio_complete (v5.8)

See upstream commit:

    block: remove the error argument to the block_bio_complete tracepoint

    The status can be trivially derived from the bio itself.  That also avoid
    callers like NVMe to incorrectly pass a blk_status_t instead of the errno,
    and the overhead of translating the blk_status_t to the errno in the I/O
    completion fast path when no tracing is enabled.
