[PATCH] eeprom: idt_89hpesx: remove redundant variable csrval_len

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Variable csrval_len is being assigned but is never used hence it is
redundant and can be removed.

Cleans up clang warning:
warning: variable 'csrval_len' set but not used [-Wunused-but-set-variable]
