[PATCH] net: phy: mediatek: fix nvmem cell reference leak in mt798x_phy_calibration

When nvmem_cell_read() fails in mt798x_phy_calibration(), the function
returns without calling nvmem_cell_put(), leaking the cell reference.

Move nvmem_cell_put() right after nvmem_cell_read() to ensure the cell
reference is always released regardless of the read result.

Found via static analysis and code review.
