compilation error in wpa_supplicant

[Narayan]

Hi All,

There is a compilation error when CONFIG_EAPOL_TEST and 
CONFIG_NO_CONFIG_WRITE flags are enabled.

-Werror gcc flag is enabled by CONFIG_EAPOL_TEST flag and is throwing 
error in wpas_p2p_store_persistent_group function. Below is the error 
message

p2p_supplicant.c: In function ‘wpas_p2p_store_persistent_group’:
p2p_supplicant.c:644:6: error: variable ‘changed’ set but not used 
[-Werror=unused-but-set-variable]
cc1: all warnings being treated as errors
make: *** [p2p_supplicant.o] Error 1
