clk: renesas: cpg-mssr: Fix use after free if cpg_mssr_common_init() failed
If cpg_mssr_common_init() fails after assigning priv to global variable
cpg_mssr_priv, it deallocates priv, but cpg_mssr_priv keeps dangling
pointer that potentially can be used later.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
Fixes: 1f7db7bbf031 ("clk: renesas: cpg-mssr: Add early clock support")
