[PATCH 02/10] network: pass scan_bss into network_load_psk

[James Prestwood <prestwoj@gmail.com>]

For adding SAE password identifiers the capability bits need to be
verified when loading the identifier from the profile. Pass the
BSS object in to network_load_psk rather than the 'need_passphrase'
boolean.
