Will McVickerandGreg Kroah-Hartman 4d29a6dcb5 clk: samsung: Fix UBSAN panic in samsung_clk_init() ...

[ Upstream commit d19d7345a7 ]

With UBSAN_ARRAY_BOUNDS=y, I'm hitting the below panic due to
dereferencing `ctx->clk_data.hws` before setting
`ctx->clk_data.num = nr_clks`. Move that up to fix the crash.
