[PATCH] kselftest/arm64: Enumerate SME rather than SVE vector lengths for za_regs

[PATCH] kselftest/arm64: Enumerate SME rather than SVE vector lengths for za_regs

[Mark Brown]

The za_regs signal test was enumerating the SVE vector lengths rather than
the SVE vector lengths through cut'n'paste error when determining what to
test. Enumerate the SME vector lengths instead.

*sigh*  SME.
