FIX: Import mmap into inner function for all_fsl_pipeline

[gjcooper]

Rationale:

Similar to pull request #1831 (and follow up to #1796) there was a function level import for NUMPY_MMAP that was missing, causing a NameError

Changes proposed in this pull request

• import NUMPY_MMAP into _gen_index [inner function of all_fsl_pipeline]
