features/trash: wind mkdir with special pid

Recent changes done w.r.t handling of mkdir calls in posix translator
resulted in crashing the brick process from trash translator. This was
due to the changes made in posix translator to return EPERM for every
mkdir calls without 'gfid-req' set in dictionary. In order to avoid
gfid mismatches during directory creation from brick side trash
translator does not set 'gfid-req'. This patch is to have an exemption
for trash based on a special pid set for those mkdir calls originating
from trash translator and to reset it in callback.

This patch also includes a small optimization to the existing test case for trash feature.
