bus: mhi: ep: Add missing state_lock protection for mhi_state access
The mhi_cntrl->mhi_state field should be protected by state_lock to
ensure atomic state transitions. However, mhi_ep_power_up() access
mhi_state without holding this lock, which can race with concurrent state
transitions and lead to state corruption.
Add proper state_lock protection around mhi_state access.

Fixes: f7d0806bdb1b3 ("bus: mhi: ep: Add support for handling SYS_ERR condition")
