This commit fixes a bug that was caused by an invalid capture of the Array class in the destructor of the mapped_ptr function. This caused intermittent errors when using the getMappedPtr function.
Fixes a bug in getMappedPtr where the Array object was not ready and needed to be evaluated when the map function was called. This appeared when the LHS or the RHS of the matmul function were JIT nodes and were sparse Arrays.

This commit fixes a bug that was caused by an invalid capture of
the Array class in the destructor of the mapped_ptr function. This
caused intermittent errors when using the getMappedPtr function.
Description
This commit fixes a bug in the getMappedPtr function of the OpenCL
Array class. The bug was caused because we were capturing the
Array class using the
thispointer instead of specifically capturingthe Buffer_ptr object. These changes are necessary because the
clEnqueueUnmap function failed to execute for CPU backends and
causes segfaults in certain scenarios.
This PR can be backported to older versions.
