clk: samsung: Fix UBSAN panic in samsung_clk_init()

CVE-2025-39728

Description

In the Linux kernel, the following vulnerability has been resolved:

clk: samsung: Fix UBSAN panic in samsung_clk_init()

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.

UBSAN: array index out of bounds: 00000000f2005512 [#1] PREEMPT SMP
