Gilles Peskine 33d816aff9 Fix stack buffer overflow in net functions with large file descriptor
Fix a stack buffer overflow with mbedtls_net_recv_timeout() when given a
file descriptor that is beyond FD_SETSIZE. The bug was due to not checking
that the file descriptor is within the range of an fd_set object.

Fix #4169
