MIPS: uaccess: Add micromips clobbers to bzero invocation

commit b3d7e55c3f886493235bfee08e1e5a4a27cbcce8 upstream.

The micromips implementation of bzero additionally clobbers registers t7
& t8. Specify this in the clobbers list when invoking bzero.

Fixes: 26c5e07d1478 ("MIPS: microMIPS: Optimise 'memset' core library function.")
