block: uapi: Fix compilation errors using ioprio.h with C++

The use of the "class" argument name in the ioprio_value() inline
function in include/uapi/linux/ioprio.h confuses C++ compilers
resulting in compilation errors such as:

/usr/include/linux/ioprio.h:110:43: error: expected primary-expression before ‘int’
  110 | static __always_inline __u16 ioprio_value(int class, int level, int hint)
      |                                           ^~~

for user C++ programs including linux/ioprio.h.

Avoid these errors by renaming the arguments of the ioprio_value()
function to prioclass, priolevel and priohint. For consistency, the
arguments of the IOPRIO_PRIO_VALUE() and IOPRIO_PRIO_VALUE_HINT() macros
are also renamed in the same manner.
