session: Fix crash when the UCI option 'password' or 'username' is missing

Browse Source 
Add a check in 'ptr.o' to prevent a crash in the
'if (ptr.o->type != UCI_TYPE_STRING)' statement
when ptr.o is null. This issue occurs due to the
absence of 'password' or 'username' in the login
section of /etc/config/rpcd.
