Fix MTE support from causing unused variable warnings
assert() calls are removed in release builds, and if that assert call is
the only use of a variable, an unused variable warning will be triggered
in a release build. This patch fixes this problem when
CTX_INCLUDE_MTE_REGS by not using an intermediate variable to store the
results of get_armv8_5_mte_support().
