The HW_VAR_BCN_FUNC case in SetHwReg8188EU() just calls
hw_var_set_bcn_func(). Remove HW_VAR_BCN_FUNC from SetHwReg8188EU(),
remove hw_var_set_bcn_func() and call rtw_write8() directly.
Since hw_var_set_bcn_func() was always called with value 0, we only
need to keep the else arm of the if statement that checks the value.

After several patches sent by the community along the last couple of
years, it's possible to remove the coding style item from the TODO file
in the driver's folder.
This patch addresses the last code formatting inconsistences and remove
the coding style item from the TODO file.

Make use of the struct_size() helper instead of an open-coded version,
in order to avoid any potential type mistakes or integer overflows that,
in the worst scenario, could lead to heap overflows.
Also, address the following sparse warnings:
