    Revert "Add extra EINVAL information about wrong block size to read(2)/write(2)"
    
    This reverts commit 1c2be25f6080ee63baeae55e45761e1310d1b756.
    
    kib@ pointed out that it is perfectly fine to write at arbitrary regular
    file offsets. For example, in a 4K block size character device, geom
    doesn't support writing / reading 515 byte blocks. The description is
    perhaps not applicable to all EINVALs returned.
