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. Also, if
posix_fd_ctx_get() failed with ENOENT, convert it into EBADF because
ENOENT is not a valid error for an fd operation.
