zram: rename ZCOMP_PARAM_NO_LEVEL

zram: rename ZCOMP_PARAM_NO_LEVEL

Patch series "zram: support algorithm-specific parameters".

This patchset adds support for algorithm-specific parameters.  For now,
only deflate-specific winbits can be configured, which fixes deflate
support on some s390 setups.

This patch (of 2):

Use more generic name because this will be default "un-set"
value for more params in the future.
