largefiles: avoid redundant loop to eliminate None from list
Before this patch, this code path contains two loops for m._files: one
for replacement with standin, and another for elimination of None,
which comes from previous replacement ("standin in wctx or
lfdirstate[f] == 'r'" case in tostandin()).
These two loops can be unified into simple one "for" loop.
