Sergei Shtylyov 1a05d8ba21 mtd: cfi_cmdset_0002: fix delayed error detection on HyperFlash
commit c15995695ea971253ea9507f6732c8cd35384e01 upstream.

The commit 4844ef8030 ("mtd: cfi_cmdset_0002: Add support for polling
status register") added checking for the status register error bits into
chip_good() to only return 1 if these bits are 0s.  Unfortunately, this
means that polling using chip_good() always reaches a timeout condition
when erase or program failure bits are set. Let's fully delegate the task
of determining the error conditions to cfi_check_err_status() and make
chip_good() only look for the Device Ready/Busy condition.
