qla2xxx: Replace two macros with an inline function

Replace the QLA82XX_ADDR_IN_RANGE() and QLA8044_ADDR_IN_RANGE() macros
with the inline function addr_in_range(). This avoids that the compiler
reports the following warning when building with W=1: comparison of
unsigned expression >= 0 is always true.
