arm64/fpsimd: Remove spurious check for SVE support
There is no need to check for SVE support when changing vector lengths, even if the system is SME only we still need SVE storage for the streaming SVE state. Fixes: d4d5be94a878 ("arm64/fpsimd: Ensure SME storage is allocated after SVE VL changes") Signed-off-by: Mark Brown <broonie@kernel.org> Link: https://lore.kernel.org/r/20240115-arm64-sve-enabled-check-v1-1-a26360b00f6d@kernel.org Signed-off-by: Will Deacon <will@kernel.org>
