[PATCH -next] Input: melfas_mip4 - remove set but not used variables

[YueHaibing]

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/input/touchscreen/melfas_mip4.c: In function 'mip4_report_touch':
drivers/input/touchscreen/melfas_mip4.c:474:5: warning: variable 'size' set but not used [-Wunused-but-set-variable]
drivers/input/touchscreen/melfas_mip4.c:472:5: warning: variable 'pressure_stage' set but not used [-Wunused-but-set-variable]
drivers/input/touchscreen/melfas_mip4.c:469:7: warning: variable 'palm' set but not used [-Wunused-but-set-variable]
drivers/input/touchscreen/melfas_mip4.c:468:7: warning: variable 'hover' set but not used [-Wunused-but-set-variable]

They are never used so can be removed.
