Dan Williams 56c30ba7b3 vfs, fdtable: Prevent bounds-check bypass via speculative execution
'fd' is a user controlled value that is used as a data dependency to
read from the 'fdt->fd' array.  In order to avoid potential leaks of
kernel memory values, block speculative execution of the instruction
stream that could issue reads based on an invalid 'file *' returned from
__fcheck_files.
