Number of cpu is not adapted for fastp tool

[mAGLAVE]

Description of the bug

Hello,
The number of cpu for fastp is not adapted. The --thread option is for worker threads only. Not for all threads used by the tool.

OpenGene/fastp#169:

--thread 2 means use 2 processing worker threads.
Besides the worker threads, fastp uses one master thread, one loader thread, and one or two writer thread (depends on SE or PE).

So it should be --thread (( $task.cpus - 3 )) in nf-core-smrnaseq/2.2.1/modules/nf-core/fastp/main.nf, line 42.

This is actually something we should address upstream in https://github.com/nf-core/modules
