vt: keyboard: Allocate new_map with ARRAY_SIZE()

In preparation for converting the kmalloc family of allocators to the
type-aware kmalloc_obj family, we need to make sure that the returned
type from the allocation matches the type of the variable being
assigned. (The kmalloc family returns "void *", which can be implicitly
cast to any pointer type.)

The new key map has as many entries as plain_map, but the size was taken
from the whole array, which would make the allocation type a pointer to
the array rather than the "unsigned short *" being assigned. Allocate
ARRAY_SIZE-many entries instead. The resulting allocation size is the
same.

Build tested ARCH=x86_64 allmodconfig with GCC 16.2.0:
drivers/tty/vt/keyboard.o
