pinctrl: qcom: msm: Fix deadlock in pinmux configuration

Replace disable_irq() with disable_irq_nosync() in msm_pinmux_set_mux()
to prevent deadlock when wakeup IRQ is triggered on the same
GPIO being reconfigured.

The issue occurs when a wakeup IRQ is triggered on a GPIO and the IRQ
handler attempts to reconfigure the same GPIO's pinmux. In this scenario,
msm_pinmux_set_mux() calls disable_irq() which waits for the currently
running IRQ handler to complete, creating a circular dependency that
results in deadlock.

Using disable_irq_nosync() avoids waiting for the IRQ handler to
complete, preventing the deadlock condition while still properly
disabling the interrupt during pinmux reconfiguration.
