regulator: rpmh-regulator: fix rpmh_regulator_init_vreg_supply memory leak

Browse Source 
Commit 29c41d5c47cb ("regulator: rpmh-regulator: support parent
supply specification in subnodes") introduced a memory leak in
the function rpmh_regulator_init_vreg_supply() due to 'buf' not
being freed in the new 'else if' statement.  Fix this memory leak
by freeing 'buf' correctly.
