pinctrl: Duplicate user memory in one go in pinmux_select()
Current code is suboptimal in three ways:
1) it explicitly terminates the string which is not needed;
2) it might provoke additional faults, because asked lenght might be
bigger than the real one;
3) it consumes more than needed lines in the source.
Instead of using kmalloc() + strncpy_from_user() + terminating, just
utilize memdup_user_nul().
