This is somewhat of a repeat of D66658 but for sections in PT_TLS segments. Although such sections don't need to be aligned such that address and offset are congruent modulo the page size, they do need to be congruent modulo the segment alignment, otherwise the whole PT_TLS will be unaligned. We therefore use the normal calculation to determine the section's address within the PT_LOAD rather than bailing out early due to being SHT_NOBITS.
