Descriptions of mbedtls_net_connect should match

[irwir]

Suggested enhancement

mbedtls/library/net_sockets.c

Line 156 in 48d1c14

* Initiate a TCP connection with host:port and the given protocol

This description mentions only TCP connection, while there is no such claim in the header file, and the function can create sockets both for TCP and UDP.

Justification

The current description might be misleading.
