[Minios-devel] [UNIKRAFT/LWIP PATCH] liblwip: Remove vfscore_put_fd from socket_close

[Sharan Santhanam <sharan.santhanam@xxxxxxxxx>]

This patch fixes a bug in the function sock_net_close. The close
function frees up a descriptor that was removed by fdrop. The fdrop
function invokes the close callback after it had removed the fd
from its list.
