correct typo in BLOCK.md

[jaromil]

small typo correction in BLOCK.md where RedisModule_IsBlockedTimeoutRequest needs to be called like a function (with ctx as argument) inside the if test.

Yo @jaromil

The docs here are copied (and outdated) from upstream - in this case the redis-doc repo.

hi @itamarhaber! ACK, I see, you mean this file here is the upstream https://github.com/antirez/redis-doc/blob/f2590e156d329cfe801399dc194d3baedfde550b/topics/modules-blocking-ops.md the typo is there too, maybe will refile and in any case refer to @antirez' redis-doc in future

[jaromil]

BTW, since I have your attention :^) still a topic about redis modules: would love to have more feedback about this redis/redis#6125 which is vital to the module I'm working on.

WRT redis-doc - yep.
WRT dlopen - I really don't know, but I'll ask the gang to opine.
