Use the MODULE_NAME_LEN definition in module_exists() to obtain the maximum
size of a module name, instead of using MAX_PARAM_PREFIX_LEN. The values
are the same but MODULE_NAME_LEN is more appropriate in this context.
MAX_PARAM_PREFIX_LEN was added in commit 730b69d225 ("module: check
kernel param length at compile time, not runtime") only to break a circular
dependency between module.h and moduleparam.h, and should mostly be limited
to use in moduleparam.h.
