J. Nick KostonandClaude Opus 4.6 de76dfd117 [wifi] Fix ESP8266 DHCP state corruption from premature dhcp_renew() 
wifi_apply_hostname_() calls dhcp_renew() on all interfaces with DHCP
data, including when WiFi is not yet connected. lwIP's dhcp_renew()
unconditionally sets the DHCP state to RENEWING (line 1159 in dhcp.c)
before attempting to send, and never rolls back the state on failure.

This corrupts the DHCP state machine: when WiFi later connects and
dhcp_network_changed() is called, it sees RENEWING state and calls
dhcp_reboot() instead of dhcp_discover(). dhcp_reboot() sends a
broadcast DHCP REQUEST for IP 0.0.0.0 (since no lease was ever
obtained), which can put some routers into a persistent bad state
that requires a router restart to clear.

This bug has existed since commit 072b2c445c (Dec 2019, "Add ESP8266
core v2.6.2") and affects every ESP8266 WiFi connection attempt. Most
routers handle the bogus DHCP REQUEST gracefully (NAK then fallback
to DISCOVER), but affected routers get stuck and refuse connections
from the device until restarted.

Fix: guard the dhcp_renew() call with netif_is_link_up() so it only
runs when the interface actually has an active link. The hostname is
still set on the netif regardless, so it will be included in DHCP
packets when the connection is established normally.
