Ivan Stepchenko a713ba7167 drm/amdgpu: Fix potential NULL pointer dereference in atomctrl_get_smc_sclk_range_table 
[ Upstream commit 357445e28ff004d7f10967aa93ddb4bffa5c3688 ]

The function atomctrl_get_smc_sclk_range_table() does not check the return
value of smu_atom_get_data_table(). If smu_atom_get_data_table() fails to
retrieve SMU_Info table, it returns NULL which is later dereferenced.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

In practice this should never happen as this code only gets called
on polaris chips and the vbios data table will always be present on
those chips.
