Fix Issue 1371: INotify server raising an error when removing a file

When a file is deleted via hg rm <file> the dirstate marks the file with
a status of 'r'. The physical file has been deleted, but INotify server.py
tries to do a stat on the file after it's been removed. Patch adds a check
for to ensure INotify doesn't do a stat on these files.
