staging: comedi: comedi_buf: factor out new buffer allocation code
The function comedi_buf_alloc() first frees any allocated buffer then,
optionally, allocates a new buffer.
Factor out the new buffer allocation code to a new function. This
allows reducing the indent level and makes the code a bit cleaner.
Also, cleanup to factored out code to make it a bit more concise.
Use a local variable for the current comedi_buf_page being allocated.
This cleans up the ugly line breaks used to keep the lines < 80 chars.
Move the #ifdef'ery for the page protection determination out of the
vmap() call.
