firmware: qcom: uefisecapp: Annotate acquiring locks for context tracking

qcuefi_acquire() and qcuefi_release() end with mutex locked or unlocked
respectively, so annotate them so the lock usage will be tracked by
context tracking tools.

Note that mutex is tracked since commit 370f0a345a70 ("locking/mutex:
Support Clang's context analysis").
