clk: xilinx: vcu: unregister pll_post only if registered correctly
If registration of pll_post is failed, it will be set to NULL or ERR,
unregistering same will fail with following call trace:
Unable to handle kernel NULL pointer dereference at virtual address 008
pc : clk_hw_unregister+0xc/0x20
lr : clk_hw_unregister_fixed_factor+0x18/0x30
sp : ffff800011923850
...
Call trace:
clk_hw_unregister+0xc/0x20
clk_hw_unregister_fixed_factor+0x18/0x30
xvcu_unregister_clock_provider+0xcc/0xf4 [xlnx_vcu]
xvcu_probe+0x2bc/0x53c [xlnx_vcu]
