mips: remove incorrect blas_lock implementations 

MIPS 32-bit currently has an empty blas_lock implementation which is
worse than nothing at all. MIPS 64-bit does has a blas_lock
implementation but is broken. Remove them and fallback to the generic
version in common.h which should do the right thing on MIPS.
