fix pico-serprog build error on gcc 16

baud is already global. no need to pass it here.
gcc 16 is much stricter, so this resulted in a
warning that lead to a build error.

this patch fixes it.

+Subject: [PATCH 1/1] fix build error: enable_spi(baud)
+
+baud is a global variable in this code. we don't
+need to pass it here. i think riku added this by
+mistake.
+
+it would have resulted in a warning before, on
+older compilers, but would have still compiled.
+
+on gcc 16, it fails with a build error. no worries.
+semantically different with this change, but behaviour
+remains the same.
+
+this fixes the build on gcc16, tested in arch linux.
