msm: kgsl: Use per page cache operation instead of bulk cache operation
For any cache operation, the current code tries to map all pages to the
kernel using vmap in case sg table is not available and then performs
the requested cache operation. If vmap fails because of memory crunch
ioctl just returns failure.
This change avoids using vmap and performs per page cache operation
even when sg table is not available. This is done to avoid failures
because of vmap especially on 32 bit systems.
