iommupt: Actually correct pt_test_sw_bit_{acquire_release}() parameter description

In review comment for v1 of genpt documentation fixes [1], Randy
suggested that pt_test_sw_bit_acquire() parameters description
should be written using "to read". Commit e4dfaf25 ("iommupt:
Describe @bitnr parameter"), however, misunderstood the review by
instead using "to read" on @bitnr parameter on both
pt_test_sw_bit_acquire() and pt_test_sw_bit_release().

Actually correct the description.
