[PATCH] SCSI: Don't attempt to send extended INQUIRY command if skip_vpd_pages is set

If a device has the skip_vpd_pages flag set we should simply fail the
scsi_get_vpd_page() call.

    n_tty: Fix buffer overruns with larger-than-4k pastes
    
    readline() inadvertently triggers an error recovery path when
    pastes larger than 4k overrun the line discipline buffer. The
    error recovery path discards input when the line discipline buffer
    is full and operating in canonical mode and no newline has been
    received. Because readline() changes the termios to non-canonical
    mode to read the line char-by-char, the line discipline buffer
    can become full, and then when readline() restores termios back
    to canonical mode for the caller, the now-full line discipline
    buffer triggers the error recovery.
    
    When changing termios from non-canon to canon mode and the read
    buffer contains data, simulate an EOF push _without_ the
    DISABLED_CHAR in the read buffer.
    
    Importantly for the readline() problem, the termios can be
    changed back to non-canonical mode without changes to the read
    buffer occurring; ie., as if the previous termios change had not
    happened (as long as no intervening read took place).
    
    Preserve existing userspace behavior which allows '\0's already
    received in non-canon mode to be read as '\0's in canon mode
    (rather than trigger add'l EOF pushes or an actual EOF).
    
    Patch based on original proposal and discussion here
