[PATCH v2 4/5] selftests/arm64: Fix MTE prctl TAP plan

From: Muhammad Usama Anjum

Date: Fri Aug 21 2026 - 10:21:56 EST


The MTE prctl test emits one result from check_basic_read() followed by
one result for each of the seven entries in mte_modes[]. However, the TAP
plan only accounts for the array entries, producing:

# Planned tests != run tests (7 != 8)

Include the basic read check in the plan so that all eight emitted results
are declared.
