commit a29b2fccf5f2689a9637be85ff1f51c834c6fb33 upstream.

smatch reports:

drivers/clk/imx/clk-imx93.c:294 imx93_clocks_probe() error: uninitialized symbol 'base'.

Indeed, in case of an error, the wrong (yet uninitialized) variable is
converted to an error code and returned.
Fix this by propagating the error code in the correct variable.

Fixes: e02ba11b45764705 ("clk: imx93: fix memory leak and missing unwind goto in imx93_clocks_probe")
