clk: qcom: clk-aop-qmp: use correct name pointer before clock registration



clk_aop_qmp_prepare() is called from aop_qmp_clk_probe() before
devm_clk_register() is called.  This means that clock hw->core
pointers are NULL and clk_hw_get_name(hw) triggers a NULL pointer
dereference.  Use hw->init->name instead of clk_hw_get_name(hw)
to avoid the NULL pointer dereference.
