[PATCH v2] common/unlzo: address violation of MISRA C Rule 7.3

[PATCH v2] common/unlzo: address violation of MISRA C Rule 7.3

[Alessandro Zucchelli]

This addresses violations of MISRA C:2012 Rule 7.3 which states as
following: the lowercase character `l' shall not be used in a literal
suffix.

The file common/unlzo.c defines the non-compliant constant LZO_BLOCK_SIZE with
having a lowercase 'l'.
It is now defined as '256*1024L'.

No functional change.

Changes from v1:
Instead of deviating /common/unlzo.c reports fro Rule 7.3 they are addressed by
changing the non-compliant definition of LZO_BLOCK_SIZE.
