net: stmmac: move frag_size handling out of spin_lock
The upcoming patch will extract verification logic into a new module,
MMSV (MAC Merge Software Verification). MMSV will handle most FPE fields,
except frag_size. It introduces its own lock (mmsv->lock), replacing
fpe_cfg->lock.
Since frag_size handling remains in the driver, the existing rtnl_lock()
is sufficient. Move frag_size handling out of spin_lock_irq_save() to keep
the upcoming patch a pure refactoring without behavior changes.
