[LAPACK] Fix stride_{a,b} descriptions in getrs_batch functionality in LAPACK domain of oneMKL (#441)

* Update getrs_batch.rst

Add missing stride_b description and update stride_a description to refer to A matrices instead of B matrices.

* Update getrs_batch_scratchpad_size.rst

Add missing stride_b description and update stride_a description to refer to A matrices instead of B matrices. Also fix formatting in stride_ipiv description.
