    Linux: normalize error return for emulated syscalls
    
    pagsh and other code expect setpag() and pioctl() to behave like
    a regular syscall or pioctl, that is to return -1 on error, with
    errno set to the specific error code.
    On Linux, the underlying emulation does a straight return of any
    error code it gets from the ioctl, and errors are not properly
    caught by the callers.
    
    As an example, pagsh won't detect an error from setpag such as
    exceeding a keyring quota limit.  With this patch, the user
    will see this:
    
    $ pagsh
    setpag: Disk quota exceeded
    sh-4.1$
    
    The code in proc_afs_syscall is modified to set errno to the error
    code and to set errorcode to -1 in case of error.
    
    proc_afs_sycall is reindented while we're changing code there.
