For ENTRY_RENAME_TRANSACTIONs, keep track separately whether the
lower_path and the higher_path have been locked, and unlock only
those which have been.

each of the subvolume
- This patch fixes bug #29.
- Using separate copies of dictionaries also eliminates a potential bug in a
setup consisting of afr with a posix and client, each having io-threads on
top as children. Since posix_xattrop after performing required operations
on the xattr array passed in dictionary, sets the result at the same key
and in the same dictionary passed as input argument,
there can be race conditions where in the results of the operation on
posix-child can be sent to the other child as input argument for xattrop,
which ofcourse is wrong.

__if_fd_pre_op_done - reset fd_ctx->pre_op_done to 0 so that double flushes do not result in two xattrop() calls

Save the original pid while locking and restore it
after the FOP is done. This ensures posix-locks can
release locks (fcntl) properly.

If a writev fails, remember it by marking it in the fd context.

Earlier the check was in afr_flush(), which caused race conditions
with writev()
