Lukas Straub 1214f72945 um: Cleanup compiler warning in arch/x86/um/tls_32.c

[ Upstream commit d27fff3499671dc23a08efd01cdb8b3764a391c4 ]

arch.tls_array is statically allocated so checking for NULL doesn't
make sense. This causes the compiler warning below.

Remove the checks to silence these warnings.
