Dag-Erling Smørgrav d09dfa2bfd Two minor optimizations of fdalloc(): ...

- if minfd < fd_freefile (as is most often the case, since minfd is
   usually 0), set it to fd_freefile.

 - remove a call to fd_first_free() which duplicates work already done
   by fdused().

This change results in a small but measurable speedup for processes
with large numbers (several thousands) of open files.
