    bpf: Update a comment
    
    This comment was introduced by fix [1], later the fix was refined by
    change [2], and the context of the usage of `m_get2()` and `m_getjcl()`
    got lost, then the comment became obscure.
    
    Update to reflect the current behavior.
    
    1. f13da24715a7 net/bpf: Fix writing of buffer bigger than PAGESIZE
    2. a051ca72e281 Introduce m_get3()
    
    Fixes:          a051ca72e281 Introduce m_get3()
    MFC after:      3 days
    
    (cherry picked from commit 343bf78e487190557889c8ba53d8080b268867f7)
