posix: use the correct op_errno
Problem: If readdir/fstat was performed on a directory that was removed, posix_fd_ctx_get() fails with ENOENT but we incorrectly use the ret value (-1 in this case) as op_errno, logging "Operation not permitted" messages in the brick logs. Also in case of fstat, the -1 op_errno was also propagated to the client via stack unwind, causing the message to appear in protocol/client logs as well. Fix: Use the right op_errno in readdir, fstat and writev.
