This patch addresses style issues reported by checkpatch.pl in
drivers/staging/rtl8712/rtl871x_io.c:

1. Avoid Multiple Assignments: The original line had multiple
   assignments in a single statement. This is generally discouraged
   for clarity and maintainability. The code has been refactored to
   use separate statements for each assignment.

2. Prefer `sizeof(*pintf_hdl->pintfpriv)` Over
   `sizeof(struct intf_priv)`: Updated the memory allocation call to
   use `sizeof(*pintf_hdl->pintfpriv)` instead of
   `sizeof(struct intf_priv)`. This is considered better practice as it
   automatically adjusts if the type of `pintf_hdl->pintfpriv` changes,
   reducing the risk of mismatches and improving maintainability.

Changes made:
- Replaced the original line with two separate lines for allocation and
  assignment.
- Updated `kmalloc` to use `sizeof(*pintf_hdl->pintfpriv)` for the
  allocation size.

These changes improve code readability and maintain consistency with
coding standards.

Hi Manisha,

please do just one change at a time. The 1. and 2. indicates that you 
are doing two different things.

Do not describe so much what you do. What you do can be seen in the 
patch. The most important thing to describe is the __why__. When 
possible just use 2-3 Lines in the description.

If you send in a second version of this patch please use a change 
history. Description from Dan under:

Thanks for your support.
