pinctrl: single: fix potential NULL dereference
Added checking of pointer "function" in pcs_set_mux().
pinmux_generic_get_function() can return NULL and the pointer
"function" was dereferenced without checking against NULL.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
Fixes: 571aec4df5b7 ("pinctrl: single: Use generic pinmux helpers for managing functions")
