x86/boot: Harmonize the style of array-type parameter for fixup_pointer() calls

The usage of '&' before the array parameter is redundant because '&array'
is equivalent to 'array'. Therefore, there is no need to include '&'
before the array parameter. In fact, using '&' can cause more confusion,
especially for individuals who are not familiar with the address-of
operation for arrays. They might mistakenly believe that one is different
from the other and spend additional time realizing that they are actually
the same.

Harmonizing the style by removing the unnecessary '&' would save time for
those individuals.
