Move the posix pending close functionality down into the VFS layer.
This hides the pending close fds from the outside. Call order
of SMB_VFS_CLOSE is reversed. Originally, it was:
fd_close -> fd_close_posix -> SMB_VFS_CLOSE -> close
And now it is:
fd_close -> SMB_VFS_CLOSE -> fd_close_posix -> close
This is in preparation of removing the fd parameter
from the SMB_VFS_CLOSE function. But it is also the right
place for the pending close calls anyways.
