lascar-el-usb: fix potential NULL dereference and memory leak

Check for successful allocation of multiple memory ranges, and release
partial allocations in the error path when one of them failed. This
fixes a potential memory leak, as well as avoids NULL dereferences.

This was reported by clang's scan-build.
