lib/bitmap.c: quiet sparse noise about address space

__bitmap_parse() and __bitmap_parselist() both take a pointer to a kernel
buffer as a parameter and then cast it to a pointer to user buffer for use
in cases when the parameter is_user indicates that the buffer is actually
located in user space.  This casting, and the casts in the callers,
results in sparse noise like the following:

warning: incorrect type in initializer (different address spaces)
  expected char const [noderef] <asn:1>*ubuf
  got char const *buf
warning: cast removes address space of expression

Since these casts are intentional, use __force to quiet the noise.
