Coccinelle warns about missing clk_put on the error path after clk_get,
but the error path returns with an ERR_PTR where clk_put must not be
called. Restructure into a single if block so the logic is clear to
silence false positive coccinelle warning.
Commit 580d952e44 ("tty: serial: bcm63xx: fix missing clk_put() in
bcm63xx_uart") previously tried to fix this same warning by adding a
clk_put, which was reverted because it was wrong.
Prevent anyone from making the same mistake again.
