clk: tegra: Drop !provider check in tegra210_clk_emc_set_rate()
The provider variable is already dereferenced earlier in this function.
Drop the check for NULL as it is impossible.
Found with smatch
drivers/clk/tegra/clk-tegra210-emc.c:131 tegra210_clk_emc_set_rate() warn: variable dereferenced before check 'provider' (see line 124)
