[PATCH 13/19] nitro_enclaves: Initialise the CPU pool mutex statically

[Alexander Graf <graf@amazon.com>]

The ne_cpus setter can run before ne_init(), when the parameter is given
at boot or to modprobe, and then takes ne_cpu_pool.mutex before
mutex_init() ran on it. Initialise the mutex in its definition instead.

Fixes: ff8a4d3e3a99 ("nitro_enclaves: Add logic for setting an enclave vCPU")
